Matrix super parity for data storage

A storage device, comprising:

• a data writer to write data to various sectors of the storage device, the storage block comprising a plurality of rows of storage sectors for a predetermined radial width on a plurality of tracks of storage media;
• and
• a storage controller configured to:
• generate down-track super parity values for data on the plurality of tracks and storing the down-track super parity values on a down-track super parity row of the storage block, and
• generate cross-track super parity values for data on the plurality of rows and storing the cross-track super parity values on a cross-track upper parity track, wherein the cross-track super parity value for any given row is generated by inputting the data on the given row into an exclusive-OR (XOR) gate.

One or more processor-readable storage media encoding processor-executable instructions for executing on a computer system a computer process, the computer process comprising:

• receiving data for storage on a storage block of a storage device, the storage block comprising a plurality of rows of storage sectors for a predetermined radial width on a plurality of tracks of storage media;
• generating down-track super parity values for data on the plurality of tracks and storing the down-track super parity values on a down-track super parity row of the storage block;
• generating cross-track super parity values for data on the plurality of rows and storing the cross-track super parity values on a cross-track upper parity track,
• wherein the cross-track super parity value for any given row is generated by inputting the data on the given row into an exclusive-OR (XOR) gate.
