Abstract
The disclosed technology provides for a method or system comprising determining size of a super block for a track zone in a storage medium based on at least one parameter of the track zone, wherein the super block includes a super parity for recovery of a failed sector within the super block.
Claims20
A method comprising:
- measuring at least one parameter from a track zone in a storage medium using a read head;
- determining a size of a super block for the track zone in the storage medium based on the at least one parameter of the track zone with a processor, wherein the super block includes a super parity for recovery of a failed sector within the super block;
- and determining a number of parity sectors for the track zone based on the at least one parameter of the track zone.
A storage device, comprising:
- a memory configured to store data;
- and a processor configured to measure at least one parameter from a track zone in a storage medium using a read head, to determine a size of a super block for the track zone in the storage medium based on the at least one parameter of the track zone, wherein the super block includes a super parity for recovery of a failed sector within the super block, and to determine a number of parity sectors for the track zone based on the at least one parameter of the track zone.
A storage device, comprising:
- a controller configured to measure at least one parameter from a track zone in a storage medium using a read head, to determine a size of a super block for the track zone in the storage medium based on the at least one parameter of the track zone, wherein the super block includes a super parity for recovery of a failed sector within the super block, and configured to determine a number of parity sectors for the track zone based on the at least one parameter of the track zone.
