Patent ID: 10971178

Abstract:
An approach to a reduced-head hard disk drive (HDD) involves a load/unload (LUL) ramp subsystem that includes a ramp assembly that includes a rotatable latch link configured for mechanical interaction with a head-stack assembly (HSA) and a LUL ramp coupled with the latch link, configured such that in response to a force applied to the latch link by the HSA, the latch link rotates which disengages a magnetic latch and drives the LUL ramp to rotate into an operational state disengaged from any recording disk of a multiple-disk stack. The subsystem may further include a motor configured to drive rotation of a lead screw to which the ramp assembly is attached, to drive vertical translation of the ramp assembly, thereby providing for loading the vertically-translatable HSA onto and off of each of the disks of the disk stack.
