Abstract:
1. An assembly comprising: a first head configured to read or write data to a first recording media surface; a second head configured to read or write data to a second recording media surface; and instructions stored in memory and implemented through a controller assembly to store data to a first extended data zone on the first recording media surface beginning at a first track zero at a first cylinder and extending to a first logical block zero cylinder on the first recording media surface, and store data to a second extended data zone on the second recording media surface beginning at a second track zero at a second cylinder different from the first cylinder and extending to a second logical block zero cylinder on the second recording media surface, wherein the first and second extended data zones are within a designated guard band zone, wherein the first logical block zero cylinder corresponds to a first track on the first recording media surface accessed by a host to read or write data, wherein the second logical block zero cylinder corresponds to a first track on the second recording media surface accessed by the host to read or write data.
