I was making a recording using a optical connection from a Sony CDP-XA30ES cd player to a Sony MDS-JA30ES minidisc deck yesterday. I am using a TDK disc that was brand new and still sealed, and the MD had been used with a lens cleaner only a month ago. Problem is when playing back on the JA30ES there are a couple of moments where the disc momentarily skips/mutes very slightly. It is in the same point on the disc, but sometimes playback is affected more than others (the length of the skip/mute). Strange thing is, I have played the same MD back on 3 other Sony decks (a MDS-JB930, a J3MD micro system and an in car player, and it plays faultlessly on all of these! With CDs certainly I have noticed that the error correction seems to be better on later (QS) models compared to their ES forerunnners, but I was wondering if this is also true for MD decks, or is it perhaps the beginnings of a more sinister problem?? Any advice would be appreciated. Thanks.
