Re: MD: MD - MD dubbing?
If you read the MDCP FAQ... I think degradation, especially on modern equipments, don't start occuring until at least the 5th generation. I've done cassette--MD--MD (all analog connections), and the last generation sounds fine. Just 1-2 generations between copies should go unnoticed even with analog connections. If I understand SCMS correctly, prerecorded MD -- optical cable -- blank MD should be all right. First generation, Norio Ohga, the (ex) Sony President who pushed for MD's creation, said openly in publications that MD has sound degradations for political reasons (or CD-R/RW music would've come out much earlier). But in your situation, it should be almost indistinguishable. Leon I've noticed HMV.com selling some of their selection MiniDisc format, which leads to an interesting question (either that or it just shows that I don't RTFM enough). If I have an MD deck with a digital out and try record to my MZ-R50, I know I can't record digitally from an MD that is a copy of a CD. Can I record from a store-bought MD to a blank MD without SCMS getting in my way? Will there be a significant amount of degradation? What I mean by degradation is... To record from CD - MD, I know that it takes uncompressed data from the CD, sends it to the down the wire in digital form, then the recorder compresses it with ATRAC, and stores it. To record from MD - MD, it uncompresses the ATRAC, sends it down the wire in digital form, then recompresses it when it hits the recorder. I know that this would cause degradation, but does anyone know if this would cause unacceptable degradation in the sound quality? Is it something that someone would even notice? - To stop getting this list send a message containing just the word "unsubscribe" to [EMAIL PROTECTED]

Your original in this case is the MD you bought in HMV, so it will be quite happy with you copying it. Will there be a significant amount of degradation? Define significant. There will be degredation, but how much and how noticeable depends how sensitive your ears are and on what is in the music! Some types of sound degrade more quickly than others but I would be surprised if you notice it. It may even be less degradation than when you record CDs. I know that this would cause degradation, but does anyone know if this would cause unacceptable degradation in the sound quality? Again, define unacceptable. I think it's fine, some people wont even notice, others will treat it like a criminal act if they can't hear an ant fart 200 miles away over the top of a heavy metal band. Is it something that someone would even notice? Possibly, it depends on the music. Having noticed it, would it really bother you? I've noticed very small differences between original CDs and copies done digitally on the JB930, but it doesn't bother me because unless I really listen for it I wouldn't have even noticed.

RE: MD: MD - MD dubbing?
Re: MD - MD dubbing, my experience has actually been with burning onto MD a copy of another MD which was digitally (optically) burned from a CD. I've done this a couple of times (original CD unavailable). Obviously SCMS did it's job well (curse it!) and prevented digital recording with a nice "impossible" message. So we burned the copy by a reasonable quality analog connection, my friends portable (MZR 30 I think) recording, my JE 520 deck playing (from memory). You'd think the result would be awful. But it wasn't/isn't. it was a bit quieter than the original MD copy, but sound quality wise I couldn't tell a difference when played back on the same deck. i still listent o those MDs. One was mono, so sound quality isn't such a big deal anyhow. By contrast another time I experimented recording from my portable E 25 to the JE 520. The result wasn't awful, but it wasn't great either - I've concluded this is because of the lack of a line out on the E25. Now while we're on the subject of MD to MD dubbing, if you have two decks with difference ATRAC, say one with ATRAC 4.5 and one with ATRAC R (or ATRAC 3 vs ATRAC 4.5), is there any consenus as to which should be recording and which should be playing? My understanding is that even with digital connections, the music still gets compressed on it's way "out" of the playing deck and compressed on it's way "in" to the recording deck. With analogue you are also dealing with A D/A converter and an A/D converter. My rule of thumb is that when dubbing betweem different machines, the best machine should be playing, because that creates the best source for recording. Anyone? - Is this right?
