Since then(prenominal) MiniDiscs obtain taken a slow start. Because everyone had comely gotten settled in with their new CD equipment, they did non want to fork out more(prenominal) cash for something that seemed like the same thing. Now people are offset to see the real payoff of MDs, and its starting to institute a little more popular. In Japan especially, prices are going down and yield is going up. I heard that in Japan, the low-end decks are around $150, and discs fuss down to $1.50, thats as cheap as a nice put down deck, and hi-bias tape. If more people start buying MD equipment in the US, we could r each(prenominal) those prices. Today, MDs in the US are kind of underground. There are a lot of people that have not heard of them yet, and not a lot of advertising. ex actly more and more I see prices going down, and more people that know about them. Well enough of the leaden stuff, here are some advantages and disadvantages.advantagesThe sound quality is great. I have never been able to identify 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 laughingstock erase the whole disc, erase one sweep, you quarter move around tracks, and put in track marks, you rump point label the disc and each track. Some formats, like DAT, can do some of these things, only MDs still have the disc establish media advantages.MiniDiscs are smaller. 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 lax discs, so you dont have to interest about them getting scratched.Its cheap. Infact I just precept a deck for $199 at Circuit City, where the cd recorders were $499. And if you look, you can find discs for $2.50 to $3.00.There just simmer down. entirely look at the equipment, 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 connectors.Of course that not all the advantages, just some of my favorite.disadvantages?MiniDiscs use compression to cut out inaudible parts of the presage, so it can fit on that little disc. Although studies show that no one can express 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 monumental in the US yet, not many pre-recorded MDs are manufactured.Those are the exclusively disadvantages I can think of, and the first one doesnt really still matter.Let me specialize you a little more about that compression.compressionMDs use a rule of compressi on called ATRAC (Adaptive Transform acoustic Coding), which only records the information audible to the human ear. It compresses the signal to One-fifth of its original size. This compression method is very similar to MPEG encoding, which is used for Mp3s. As I express 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(predicate) to a North or South pole. When the optical maser runs across these regions, it can tell whether its N or S and starts to construct the data stream.conclusionSo, all in all, MiniDiscs are a way to get CD quality recording on a compact, inexpensive, media. I love every part about MiniDiscs, and would definitely recommend them to anyone interested in high-fidelity audio in general.Sleek, stylish, and silver Not only does Sonys M Z-E909 look great on the go, but its ruffianly magnesium body weighs in at an eminently portable 1.75 ounces.In addition to portability and bright styling, you also get track navigation and playback features cool enough to satisfy even diehard MiniDisc fans.
