Method of setting up a pre-amplifier for hard disk drive and hard disk drive incorporating the same
A method of setting up a pre-amplifier for a hard disk drive and a hard disk drive incorporating the method. A serial interfacing mode of the pre-amplifier is checked by writing and reading data to/from the pre-amplifier. A chip ID of the pre-amplifier is checked and a vendor of the pre-amplifier is identified using the chip ID. Default values of the pre-amplifier stored in a ROM and adaptive codes of the pre-amplifier are automatically downloaded to a register of a hard-disk controller, simplifying the pre-amplifier installation and reducing errors which may occur during manual installation of the pre-amplifier.
