Abstract
A head-assisted magnetic recording-shingled magnetic recording (HAMR-SMR) type storage device is described that includes a control module and one or more magnetic recording layers partitioned into zones. The control module is configured to write initial data beginning at an initial logical address of a zone. The initial logical address of the zone corresponds to an initial physical address of the zone. Responsive to receiving a command from a host associated with the HAMR-SMR type storage device to reset the zone and write subsequent data, the control module is further configured to reset the initial logical address of the zone to a subsequent physical address of the zone, and after resetting the initial logical address, write the subsequent data beginning at the initial logical address of the zone.
