Hard disk onto which table information depending on model is written, and hard disk drive adopting such a disk

摘要

A hard disk on which table information varying depending on the model of a hard disk drive (HDD) is directly written includes: a hard disk assembly (HDA) having a hard disk for storing table information varying depending on the model of the HDD in a predetermined region of a data zone; and a main board having a RAM for reading and storing table information stored in the hard disk, a ROM for storing common table information irrelevant to the model of the HDD and programs for controlling the hard disk assembly and reading and writing of data, and a controller for reading and writing data according to the table information and programs stored in the RAM and ROM. Therefore, by storing table information varying depending on the model of an HDD in a disk and not in a ROM, a main ROM installed in the main PCB can be constructed with the same structure regardless of the model of an HDD, thereby simplifying the manufacturing process of the HDD.
