Abstract

An implementation of a disk drive with improved efficiency where a read head supported by a first positioning component is provided and a write head supported by a second positioning component is also provided. By positioning the write head behind the read head at a predetermined angle, the disk drive can execute a “read-before-write” or “read-modify-by-XOR-write” operation by before the platter has rotated a full revolution.
