zeroexe

Hi Everybody ^^ The situation is that I have bought a mds s38 in second-hand market for $150 HKD(around $20USD, really very cheap ) few months before. At the beginning, the machine would turned on automatically and refused to eject the disc. OK. I have found the solution to solve it. But the most hateful problem is that.... One day I have no choice but to record through Audigy 2 ZS analog-out, after i press STOP and EJECT, I 'm used to re-insert the disc, then i saw the damn word "Blankdisc"!!! No matter I record through Optical or Analog, only a blank disc will be ejected.(But FUNCTION WELL on playing) Is it caused by the aging of the optical head??How can I deal with it?? Regards.
