My Aiwa XR-H66MD quit reading CD's many months ago.
Now it won't make a decent MD recording, as a few tracks skip upon
playback.
I bet it's got Sony optical blocks in it.
I practically have to replace my Sony-based CD/MD equipment every year
just to keep it all working *sigh*.

If you are constantly replacing your equipment or had to replace equipment
with a dead power supply, I would suggest that you keep the old equipment
rather than junking it if you are into electronics tinkering and
experimenting. Some of it can be useful as parts donors. For example, you
may be able to use parts from a Sony JE520 to do elementary repairs on a
Sony JE530. Sometimes you may be able to find some parts useful for a
particular project like microswitches and rotary encoders from this kind of
equipment.
Simon,
I always keep my junked electronics for parts, or if I don't have the
heart to part it out, I sell it on Ebay. :)
I took it apart today. Luckily, I was able to fix the CD player simply
by cleaning the lens real good. I did the same to the MD recorder, hope
that fixes it. I discovered the XR-H66MD is fairly new, since it uses a
CXD2652AR ATRAC chip which is at least ATRAC 4. All calibration
parameters are also stored in EEPROM, so all adjustments will have to be
performed via a secret service mode. Anyone happen to know what the
procedure is? If it still skips during recording, I believe the problem
could easily be corrected by increasing recording laser power just a
little bit. AFAIK, it doesn't skip at all during playback (of discs
recorded on other recorders).
