CD players use a laser diode to read the disk. The player detects the presence of a disk by simply checking to see if it can read data. No data == no disk. Unfortunately, these laser diodes have a lifespan of four or five years. Tired diode == no data. Guess what? (It may be possible to crank up the drive current on the laser diode but this will only postpone the inevitable. See back issues of R-E maybe three years ago for details...) -- ---------------------------------------------------- Gordon S.
