Abstract:
A method for transferring corrected data to an external buffer within a tape drive is provided. After the receipt of data from a data recording medium, the data are stored in an external buffer. The data are then transferred from the external buffer to an error correction code (ECC) device. Any error in the data within the ECC device are corrected. The corrected data are subsequently divided into multiple sub-units, and a transfer flag is added to each of the sub-units having corrected data. Only the sub-units having corrected data are transferred from the ECC device back to the external buffer.
