willing to do that then why pay for a high-speed recorder?
Sony Semiconductor’s “Laser Diode Guide” is available from http://www.sony.net/Products/SC-HP/tec/catalog/laser.html. Laser diodes can suffer catastrophic failure (they suddenly stop working) or gradual degradation (reduced optical power for a given input power level). The power calibration sequence ((4-13), (5-11)) automatically adjusts the power supplied to the laser for a given disc and write speed, so reductions in output are compensated for automatically. However, if the laser’s efficiency is reduced, more DC power must be supplied, more heat is generated, and the likelihood of failure increases. For a discussion of laser diode reliability, see http://www.bostonlaserinc.com/art1.php.
