Abstract
A disk drive to implement write operations requested by a host is disclosed. The disk drive comprises: a disk having a plurality of tracks, wherein each track includes a plurality of physical data sectors; a head actuated over the disk; and control circuitry. The control circuitry is operable to determine if a write request from the host includes logic data that includes unaligned writes, and if so: coalesces nearby writes; performs a group read operation to create a plurality of groups; and performs a write operation to write the logic data to the physical data sectors based upon the plurality of groups, wherein the physical data sectors are written to the disk during a single revolution of the disk.
