I've got a quite expensive Harmon Kardon HD970 CD player with a facility

gather from a brief internet search that the simplest solution is to
swap out the mechanism.

I've never been that convinced by optical media - far from the 'perfect
forever' we were asked to believe.


** The phrase "perfect sound forever" was used in relation to the release of the CD disk in 1982. Nobody suggested that CD players would have an indefinite life.

Nevertheless, I still have Sony CDP101 that was purchased in May 1983. It is the only CD player I ever bought and it still functions and tests perfectly.

I also have any number of CDs that are of similar age and they all play perfectly, same as the day they were made. Same is true for every CD I own.


I'd agree on the retail music and data CDs. But not on writeable, and
certainly not rewritable. Quite a few of mine from 10+ years back can't
be read, and they've been stored in reasonably good conditions.


** The famous phrase you cited NEVER applied to either of those, as they are came along much later and were not intended for the release of commercial recordings. In fact, many doubts about longevity were expressed when they first appeared.

Wanna have a good whinge abut the weather ???
