Claim 11:
12. A magnetic disk device comprising:
a connector for connecting to the RW parameters adjustment device as an adjustment target; and
an internal memory connected to the RW parameter adjustment device to record an adjustment log indicating that the parameters are adjusted by the adjustment process; wherein
the RW parameter adjustment device performs a pre-registration process of a magnetic disk device for testing, the pre-registration process including changing conditions of a plurality of RW parameters related to read and write to determine a capacity and characteristics for each of various heads of the magnetic disk device for testing to measure the characteristics and creating, for each of the heads, a database in which the measured characteristics are registered; and which performs an adjustment process of a magnetic disk device to be adjusted, the adjustment process including changing the conditions of the RW parameters for each of heads of the magnetic disk 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 among round-robin conditions by estimation of a neural network computer based on the similar characteristics of the database obtained by the searching.
