Disk drive including I-regions having configurable final logical block addresses

摘要

A disk drive includes a controller and at least one disk, which may include a first I-region, a second I-region, and an E-region. The first and second I-region may have a first final logical block address (LBA) and a second final LBA, respectively. The controller may be configured to cause information to be written to the first I-region and the second I-region using a first type and a second type of magnetic recording, respectively. The controller also may be configured to set at least one of the first final LBA or the second final LBA to a final LBA value higher than the at least one of the first final LBA or the second final LBA, respectively, after writing user data to at least a portion of the first I-region or the second I-region and without removing the user data.

主权项

1. A disk drive comprising:
a controller; an environmental monitor; and at least one disk with two major surfaces, wherein the at least one disk comprises:
a first I-region having a first, factory set final logical block address; anda second I-region having a second, factory set final logical block address;wherein the controller is configured to:
cause information to be written to the first I-region using a first type of magnetic recording,cause information to be written to the second I-region using a second type of magnetic recording,receive an indication from the environmental monitor,determine, based at least in part on the indication, that a capacity of at least one of the first I-region or the second I-region may be increased to more than an original factory setting capacity, andin response to determining that the capacity of the at least one of the first I-region or the second I-region may be increased to more than the original factory setting capacity, reset at least one of the first, factory set final logical block address or the second, factory set final logical block address to a final logical block address value higher than the at least one of the first, factory set final logical block address or the second, factory set final logical block address, respectively, to increase the capacity of the at least one of the first I-region or the second I-region to more than the original factory setting capacity.
