Abstract

As personal computers and OA machines with higer level functions continue decrease in size recently, the requirements for external storage devices are becoming exacting. The 130mm magneto-optical disk drives presently used cannot necessarily meet those requirements. We have developed a 90mm magneto-optical disk drive, aiming at higher performance, small size and lower power dissipation, as well as higher reliability. The target of lower power dissipation is important in order to prevent a rise in temperature inside the drive, to realize higher-density packaging and to decrease the quantity of cooling airflow which causes the accumulation of dust.
