Abstract

A low friction load/unload device for retracting a slider from or restoring a slider to the disk of a DASD (Disk Access Storage Device), having a ball bearing mounted on the load beam to engage an inclined surface with minimum frictional forces is disclosed. Whenever the inclined surface is part of a ring which rotates with the disk, the use of the ball bearing contact is highly advantageous since it substantially reduces and may eliminate those friction or stiction forces between the load/unload device and the ring member which would inhibit disk start up and disk rotation. The incorporation of the ball bearing into a tang for engagement with the inclined surface of the ring or ramp substantially reduces forces resisting operational forces generated both by the actuator motor and disk drive motor, thereby allowing smaller motor structures to be incorporated into reduced-size DASD units.
