Techniques for emulating sequential device with constrained disk drive

摘要

A disk drive apparatus includes at least one disk, a head-arm assembly, and a controller circuit. The head arm assembly includes at least one read/write head. The head-arm assembly is movable to enable the read/write head to access a writable surface of the disk. The controller circuit also causes the read/write head to record data on the writable surface of the disk in a write append format.
