摘要:
A data writer is described comprising: a memory to store at least one amount of source data that is to be written to a data storage medium; a processor to arrange the source data into subsets and generate ECC data in respect of each subset, wherein the source data and the associated ECC data are to be written to a data storage medium via a plurality of individual data channels, and wherein the ECC data comprises at least a first degree of ECC protection having a first level of redundancy in respect of a first subset and a second degree of ECC protection having a second level of redundancy in respect of a second subset; a plurality of data writing elements, each to write data from an associated data channel, concurrently with the writing by the other data writing elements of data from respective data channels, to a data storage medium; and a controller, to control the writing by the data writing elements of the source data and the associated ECC data to the data storage medium.
