METHOD FOR OPTIMIZATION OF POSITION OF DATA ZONE AND DATA STORAGE SYSTEM

摘要

PROBLEM TO BE SOLVED: To improve the utilizing efficiency of outer circumferential parts of a disk by defining a position of a data zone of a data storage disk to be a position close to the outer circumference of the disk based on conditions of the system whose assembling is finished. SOLUTION: After assembling of system components is finished, a slider 63 is moved in a direction of an outer circumference 67 of a disk 24. Then a point on the disk 24 at which a load tongue 65 is in contact with a slope 90 of a ramp 60 and the slider 63 is parted from the surface of the disk 24 is registered as a load/ unload position 94. Furthermore, the slider 63 is moved in an inner circumferential direction and a position on the disk 24 at which the load tongue 65 is parted from the slope 90 and the slider 63 reaches an actually recording and reading enable state on the surface of the disk 24 is registered as an outermost data track 88. Formatting is conducted between the outermost data track 88 and a prescribed innermost track. The redundancy included in a buffer zone 72 in existence in common to disks in general is reduced depending on the actual conditions so as to extend the data track areas in the outer circumferential direction on the respective disks.
