I think it's rather that the motor spin-up time is slower. Motor speed itself would not seem to have a direct relation to power consumption. On the Sharp MD-MT831 the top end motor RPM (400-1350rpm) is actually higher than on mainstream units (400-900rpm), I've always assumed this was to

All this talk about the MZ-R90 taking forever to: a) read the TOC and start playing, and b) write the TOC has made me come to the preliminary conclusion that the MZ-R90/91 spins the disc at a lower rate to save power. Won't this affect shock protection? I would imagine that this would cause

It would be impossible for the R90 to actually spin the disc slower. If it did, it would not have enought headway to fill the buffer and play music. What it does, is slowly spin up the disc (smooth acceleration) instead of starting it of at full speed. That saves battery juice. So what you
