ABSTRACT:
A method for increasing data storage on a hard disk drive is disclosed herein, the method including determining a capacity goal for the disk drive, partitioning the usable disk surface on the disk drive into regions, and calculating a transfer rate based on the capacity goal and the usable disk space. The rate at which data may be transferred is then increased by a first selected quantity and/or decreased by a second selected quantity to establish a higher and/or lower transfer rate. For multiple data heads used in an individual disk drive unit, a first group of heads is partitioned from the remaining heads based on a particular selection criteria, and the remaining heads are arranged into a second group. The first group of data heads then operates at a higher transfer rate than the second group of data heads, and an algorithm for reading and writing data at the different rates is created.
