Abstract | A data storage device configured to access a magnetic tape is disclosed, wherein the data storage device comprises at least one head configured to access the magnetic tape. A first plurality of data blocks are encoded into a first plurality of ECC sub-blocks including a first ECC sub-block, and the first plurality of ECC sub-blocks are encoded into a first ECC super-block. The first ECC sub-block is written to the magnetic tape, and a write-verify of the first ECC sub-block is executed by reading the first ECC sub-block. When the write-verify passes, a second plurality of data blocks are encoded into a second ECC super-block, and when the write-verify fails, a third plurality of data blocks and the first ECC sub-block are encoded into the second ECC super-block, wherein the second ECC super-block is written to the magnetic tape. |
