Load/unload ramps for multiple disk-stack, shared actuator hard disk drive

摘要

A load/unload ramp configured for a multiple disk-stack, shared actuator hard disk drive (HDD) includes a ramp part configured for loading and unloading a head stack assembly (HSA) from multiple directions, e.g., from multiple disk stacks, and a tooling part configured to couple with an HSA handling part. The HSA handling part is useful for handling a ramp-HSA assembly during installation, such as for moving the ramp along a guide channel of an HDD base, from an initial position to a final position at which a guide channel stop is reached.

主权项

1. A multiple disk-stack, shared actuator hard disk drive comprising:
a base; a first disk media stack rotatably mounted on a first spindle; a second disk media stack rotatably mounted on a second spindle; a head slider comprising a read/write head configured to read from and to write to disk media; a voice coil actuator configured to move said head slider to access portions of at least one disk media of said first disk media stack and at least one disk media of said second disk media stack; and a ramp assembly positioned between said first disk media stack and said second disk media stack, wherein said ramp assembly comprises:
a ramp part with which said first disk media stack and said second disk media stack are interposed, anda tooling part coupled with said ramp part, said tooling part configured to couple with a head stack assembly handling part.
