If mixed with metals as an alloy it becomes strong and easy to use.Woods hard wood -this wood is harder and generally more(prenominal) durable than soft wood, there are many different colours.

Since then MiniDiscs have interpreted a slow start. Because everyone had just gotten settled in with their new CD equipment, they did not want to fork out more money for something that inspectmed like the kindred thing. Now people are starting to see the real advantage of MDs, and its starting to swallow a little more popular. In Japan especially, prices are going down and production is going up. I heard 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 people start buying MD equipment in the US, we could reach those prices. Today, MDs in the US are kind of underground. at that place are a lot of people that have not heard of them yet, and not a lot of advertising. But more and more I see prices going 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(prenominal) you record something on them, you stick out 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 discs, so you simulatet have to worry about them getting scratched.Its cheap. Infact I just saw 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 cool. Just 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 connections.Of course that not all the advantages, just some of my favorite.disadvantages?MiniDiscs use conglutination 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 lone(prenominal) disadvantages I can think of, and the first one doesnt really even matter.Let me tell you a little more about that abridgement.compressionMDs use a method of compression 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 true size. This compression method is very similar to MP EG 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 data stream.conclusionSo, all in all, MiniDiscs are a way to get CD quality recording on a compact, inexpensive, media. I have it away 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 system weighs in at an eminently portable 1.75 ounces.In addition to portability and chic styling, you also get track glide and playback features cool enough to satisfy even diehard MiniDis c fans.
