摘要：
A hybrid drive is disclosed comprising a non-volatile semiconductor memory (NVSM) comprising a plurality of blocks, and a head actuated over a disk comprising a plurality of tracks, each track comprising a plurality of data sectors. A garbage collection operation is executed on the NVSM by reading valid data from a first block of the NVSM, writing the valid data to the disk, and erasing the first block.
