Abstract
According to one embodiment, a read and write (RW) parameter adjustment method includes changing conditions of RW parameters to determine a capacity and characteristics for each of various heads of a test device to measure the characteristics and creating, for each of the heads, a database in which the measured characteristics are registered, and changing the conditions of the RW parameters for each of heads of a device to be adjusted to measure characteristics, searching the database created for each of the heads for a database having similar characteristics, and setting the capacity and characteristics in an appropriate balance based on the similar characteristics of the database obtained by the searching.
