Data storage device employing high quality metrics when decoding logical block address appended to a data sector |
摘要 |
A data storage device is disclosed that receives a read command from a host, wherein the read command comprises a read logical block address (LBA_R). A target data sector is read in response to the LBA_R to generate a read signal. The read signal is processed to detect user data and redundancy data using a soft-output detector that outputs quality metrics for the user data and redundancy data. A high quality metric is assigned to the LBA_R, and errors are corrected in the user data using an error correction code (ECC) decoder in response to the quality metrics output by the soft-output detector and the quality metrics assigned to the LBA_R.
