Abstract :
Summary form only given. Currently interest in spin-stand testing of magnetic hard disk media at elevated temperatures is mainly motivated by thermal decay issues. A temperature of 60-70/spl deg/C inside a typical disk drive can affect the stability of the medium. Other key performance parameters, such as overwrite and signal amplitude, can also be affected by the rise in temperature and should therefore be evaluated at both room and disk drive temperatures.
