Abstract
Systems, methods and computer program products for writing and reading a plurality of data sets and error codes are described. In some implementations, a magnetic disk controller can be provided that includes an error code unit configured to generate one or more error codes for each of a plurality of data sets to be written onto corresponding sectors of a medium. The magnetic disk controller can also include a buffer unit configured to store each data set and an error code in an associated buffer, and an encoding unit configured to encode the plurality of data sets. In some implementations, at least one data set is encoded concurrently with the buffer unit storing another different data set in the associated buffer. The magnetic disk controller can also include a control unit configured to write each encoded data set and a corresponding error code onto a corresponding sector.
