ABSTRACT:
Methods and systems are shown that specify at least one low track-per-inch (TPI) region and at least one normal TPI region on a disk. The low TPI region may be used to store information that may be rewritten frequently. The normal TPI region may be used to store information that may be rewritten less frequently. The low TPI region may reduce the need for adjacent-track-erasure (ATE) refresh.
