摘要： Embodiments in accordance with the present invention relate to identifying an address of user data to be registered as a defective user data address in disk defect inspection. In an embodiment of the present invention, in the state where a write element is positioned to a target position to execute data write processing to execute normal data read processing, a write element executes data write processing. If a predefined error occurs during the data write processing, an address of user data for which the normal data write processing is executed is estimated using the error-causing servo data as a target. In addition, an address of the servo data used as the target during the normal data write processing for the estimated address of the user data is identified. If the identified address of the servo data and the address of the error-causing servo data match with each other, the estimated address of the user data is registered as a defective user data address.

摘要： Embodiments in accordance with the present invention increase the reliability of a data storage device, and to reduce the circuit size. According to one embodiment of the present invention, a hard disk drive (HDD) executes not only error correction processing of data to be written to a magnetic disk, but also error correction processing of data stored in the DRAM. In the HDD according to this embodiment, one SRAM is shared by both kinds of error correction processing. As a result of executing the error correction processing of the data stored in the DRAM, the reliability of the HDD is improved. In addition, by using the same SRAM for the two kinds of error correction processing that differ from each other, it is possible to suppress the increase in circuit size.
