Recording the ShortWave Signals
Mini Disc vs. Compact Cassettes

Sony's last home Mini Disc home deck, the MDS-JE480 (discontinued in early 2008).
Sadly....Sony no longer sells a "Mini Disc" deck for the US market.

However it's not all doom and gloom for "Mini Disc" decks.
Teac sells at least one model , the rack mountable MD-350 and Onkyo has the MD-133 (Japanese Domestic model).

Very Important Note Below: When Recording "Mono" Audio With Mini Disc !!!

As I indicated on the AR7030 page, I very much like to make recordings off my shortwave receivers to enjoy the good catches again. When I first started doing this back in 1977, I was just using the good old "Compact Cassette" to archive on. How it has all changed.

Shortwave Radio Recording......Hit that "Record" button....

Just about anytime I'm hearing a signal that even sounds remotely interesting on my receivers, I automatically switched on a Reel to Reel tape deck. Most of the time was nothing, but I have had too many times where I have said, Darn..missed that. So its a natural reflex now to just hit the record. Reel to Reel had worked great to make the "Catch" off the air. Then I can edited this (if needed) down to the Mini-Disc, to really save into my archives. But now I use mini-disc totally in place of the Reel to Reel to even make "the catch" and sounds even better. No real degrade at all of the orginial reception. With the price of the Mini-Disc decks and blank disc's dropping in price big time it was time for the total change over. I can make one digital to digital copy with no problem, so now edit from one mini-disc deck to another.

The lousy "Compact Cassette"

Just as the title says, and it sure is. Oh, I have used it over the years to archive onto as it was the most easiest and smallest package that you could have used. But, as anyone knows, that uses the compact cassette format , it has way too many problems. Jammed tape in the housing (from fast fowarding and rewinding), stretched tape, dropouts (caused by the stretching), pressures pads that go sour.Cassette's are very sensitive to head alignment..and can sound wavy real easy. And of course the MAIN real problem is the actual audio quality...hiss...hiss....and more hiss. Dolby I have never liked, and does not work on SW signals well anyway. Making any dubs from Cassette to Cassette are a bad deal...quality of the recording only goes down hill. We could go on...but the point sticks, cassette's stink.

The Mini Disc format is pocket small and has more protection over a standard CD.


What is this "Weird" looking thing ??

We will not cover this directly here, but the
The Mini Disc Community Page goes over the format on what it is, with many other links, and news. In a nutshell, its a digital format, uses a laser to record and pick up the data off the disk. Using standard mode (74 min on older discs) 80 mins can be recorded (Stereo). If you don't mind a bit of "degrade" of the recording, new "LP2 and 4" and Hi-MD modes are showing up on the newest recorders (most are on portable units in the USA) that will give you hours and hours on ONE disc. Most newer Decks have a "Mono" mode which double the recording times (cannot be used with the new LP or Hi-MD modes). Being I use Mini Disc for recording shortwave signals this is what I of course use, and can get up to 160 mins of recording time on just one disk using the standard mode. Access is just like on a CD...so no more Fast Forward and Rewinding to hunt down a segment. Just like a CD, you can have tracks (any way YOU want it).

You can also put alpha tags on each one of these track's . Again, you are able to make one Digital to Digital dub (Mini-Disc's have a copy protection for digital to digital copies , you can make one),so a back up sounds just as good as the first. As far as storage goes, you can put 16 of these in some 3 by 5 Index Card boxes.

Why not (CD) CDR-CDRW or even MP3's ??

Still not won over....read these comments from Ken Pohlmann (this is a bit dated now).

MiniDisc: Roll Your Own
by Ken C. Pohlmann

With literally thousands of commercial recordings available there should be a recording to meet even the most obscure taste. Add in new releases, re-issues, retrospectives, and collections and the selection is infinite. But even with all that is currently available in the pre-recorded format, many folks still feel compelled to roll their own. Simply by using that red record button, you can have Zappa, Beethoven, Everclear, Led Zeppelin, Boys II Men and Bach jamming together. Hey, why not? For legal, private use, copying can increase your music collection considerably.

There are a couple of ways to make copies. Most people are content to make cassette tapes. However, cassette copies don't always sound very good, they wear out, and in general, are low-tech. A few people make their own CD recordings, buying blank discs and a CD-R recorder. However, these recorders are relatively rare, and CD-R recording is unforgiving. If you make a mistake and record something you don't want, it remains on the disc forever (even though you can skip over it). Although cassette and CD-R are great, the recordist's dreams are perhaps best answered by the MiniDisc.

The MiniDisc was specifically designed for two things: to allow people to make their own recordings, and then take those recordings with them. The MiniDisc is thus very easy to use, extremely flexible in its recording and playback abilities, and extremely portable. In fact, there is a lot to like about the MiniDisc. It is small and cute. It is both writable and erasable, and provides fast random access and robust shock-resistant portability. A MD recorder uses a data compression algorithm called ATRAC to store 80 minutes of music (many recorders let you optionally record 160 minutes of mono audio). The ATRAC algorithm has been steadily improved, and most listeners cannot hear a difference between a CD and a MD, especially in the portable environments where MD is at its strongest. Whether it is as a home player/recorder, car player, or shirt-pocket player, MD has many applications.

Making a MD recording is extremely easy. In many cases the source player and the recorder can be interconnected, allowing one-button operation. Simply put in your source, and a blank disc, and hit the record button. If you want to compile a number of songs from different albums, you'll will have to swap from one source to another, but its pretty painless. If you can operate a microwave oven, you can make your own MD recordings.

MD offers a number of very interesting perks. Virtually all MD recorders let you enter an alphanumeric title for the MD disc, as well as titles identifying each song and artist. Using a keypad or a jog wheel, you simply dial in the titles you want, and they are permanently stored on the disc. Then, each time you play the MD, the titles scroll across a display. This is especially convenient if you have put together a diverse compilation. Many recorders let you skip through the song title list (instead of track numbers) to find the song you're looking for. This is a great feature.

Most MD recorders also let you perform very sophisticated editing on recorded material. A MD disc is a lot like a computer hard disk; the data is stored on disk in whatever order it happens to fit. In many cases, songs are not recorded continuously; the data is simply picked up from wherever it is, and played back continuously. This makes the MD very flexible. For starters, when adding a song to a partly-recorded disc, you don't have to find the end of the last recording. You simply hit the record button, and the recorder puts the data wherever there is room (this is a revelation to those accustomed to the hassles of making tape recordings). Once you have recorded material, you can edit it. For example, most recorders let you move tracks (changing their order) or move segments of tracks. You can also erase all or part of a disc, and divide a track into smaller tracks, or join several tracks into longer tracks. In many ways, a MD recorder is like a miniature recording studio. With a little practice, you'll be able to make amazingly good custom recordings. Of course, if you make a mistake, or simply get tired of a recording, you can simply hit the erase button and start over.

MiniDisc is truly a recordist's dream come true. Using its powerful recording and editing features, you can make professional-sounding recordings. If you like music, and you want it YOUR WAY, then check out MiniDisc recorders and players.

When Recording "Mono" Audio (using the mono mode) With Mini Disc !!! MOST IMPORTANT NEWS HERE ...read on !!

Many will already know what I'm talking about here, but for others who might not !!

Here is one that just about dropped me to the floor when I discovered this. Actually this is really a no brainer..but cannot beleive that it took me this long to discover what was going on here.

I had thought that the mono mode in these MD decks were a bit better mixing for mono signals using "stereo" PRE-AMPED outputs....I was WRONG....no way !!! If you keep the decks in stereo mode this of course would not be a problem.

I use the "mono" mode almost most of the time for recording off the shortwave broadcast bands. So of course I use the "mono" mode on the mini-disc decks just about full time.

You never want to make a mono signal using a "y-cord" on the source using any active PRE-AMPED stereo output !!! Say from a mixer or another tape deck etc.. This will throw the audio signal out of phase and kill the quality of the signal.

Throwing the MD decks in 'mono" (using a normal dual stereo patch cable) is doing this same thing , so don't do it this way !!!

The cure when using "mono" mode on MD decks...is to just be sure to take "one signal" L OR R from the source say via a mixer, other deck etc..., and now here use a Y-cord on the back of the MD line input to feed the SAME identical signal to both L and R on the MD deck. For most that are using only one SW set direct to the MD deck that only has one channel and not using a mixer or any other stereo"pre-amped" electronics....etc..this will not be a problem.

The real stinker is if you are recording music, say some old "mono" 45's, and if you come out analog via a stereo receiver or mixer and go into you MD disc using mono mode, you better just use one (L OR R channel) and/or Y-cord it to the MD deck. If you don't you will cut off a good chunk of your high end...
