Since then MiniDiscs have taken a slow start. Because everyone had just gotten settled in with their impertinently CD equipment, they did non want to fork out more money for something that seemed like the homogeneous thing. Now community are starting to see the real benefit of MDs, and its starting to depart a elflike more popular. In lacquer especially, prices are going down and production is going up. I comprehend that in Japan, the low-end decks are around $150, and discs get down to $1.50, thats as cheap as a nice tape deck, and hi-bias tape. If more commonwealth start buying MD equipment in the US, we could reach those prices. Today, MDs in the US are kind of underground. There are a lot of people that have non heard of them yet, and not a lot of advertising. provided more and more I see prices g oing down, and more people that know about them. Well enough of the boring stuff, here are some advantages and disadvantages.advantagesThe sound quality is great. I have never been able to tell a difference between MDs and a CD or DAT. MiniDiscs have an advantage to CD-Rs in that after you record something on them, you arse erase the whole disc, erase one track, you can move around tracks, and put in track marks, you can until now label the disc and each track. Some formats, like DAT, can do some of these things, but MDs still have the disc based media advantages.MiniDiscs are microscopicer. The Discs are 7cm x 7cm, and the portable recorders can be smaller than cassette walkmans.The discs are encased in a plastic shell, much like floppy disk discs, so you dont have to worry about them get scratched.Its cheap. Infact I just saw a deck for $199 at go City, where the cd recorders were $499. And if you look, you can find discs for $2.50 to $3.00.There just cool. Just look at the e quipment, who wouldnt want to have this stuff.And, as of all digital formats, you can make a digital copy from any digital source through coaxial or optical connections.Of course that not all the advantages, just some of my front-runner.disadvantages?MiniDiscs use compression to cut out inaudible parts of the signal, so it can fit on that little disc. Although studies show that no one can tell the difference, some people want all of there precious signal.Its hard to find equipment and pre-recorded MDs. I live in Jefferson City, Mo which is a pretty small town, so I have to go to the Big Cities to get stuff. Also, since MiniDiscs arent that big in the US yet, not many pre-recorded MDs are manufactured.Those are the only disadvantages I can think of, and the first one doesnt really even affair.Let me tell you a little more about that compression.compressionMDs use a method of compression called ATRAC (Adaptive Transform Acoustic Coding), which only records the information audible t o the human ear. It compresses the signal to One-fifth of its original size. This compression method is very kindred to MPEG encoding, which is used for Mp3s. As I said before, people have compared MDs, CDs, and DAT, and not been able to tell any difference.I bet your asking yourself, but how does it record? Well, Im about to tell you.recordingMDs use a special Magento-Optical method that magnetizes regions of the discs 60 millionth of a cm apart to a North or South pole. When the laser runs across these regions, it can tell whether its N or S and starts to construct the selective information stream.conclusionSo, all in all, MiniDiscs are a way to get CD quality recording on a compact, inexpensive, media. I hunch forward every part about MiniDiscs, and would definitely recommend them to anyone interested in Hi-Fi audio in general.Sleek, stylish, and silver Not only does Sonys MZ-E909 look great on the go, but its rugged magnesium automobile trunk weighs in at an eminently portab le 1.75 ounces.In addition to portability and overbold styling, you also get track navigation and playback features cool enough to come across even diehard MiniDisc fans.
