摘要： A magnetic data embedding system (or disk servo writer) includes a stack with a master disk (3) and a plurality of magnetic disks (4) mounted on a shaft of a spindle motor (6), and a rotary positioner (11) which integrally holds one or more read-only heads (71 to 74) for reading the master disk and a plurality of groups of servo heads (101 to 104) and which simultaneously turns both of the kinds of heads. The groups of servo heads have access to the top and bottom sides of the magnetic disks. The servo heads are made carry out writing to the same (top or bottom) side of each of the disks in parallel, within assigned track ranges for the respective servo heads. In order to make the servo heads on the same side of the disks carry out writing correctly in their assigned track ranges in several of the disclosed embodiments, an address correction data memory (23) supplies information about track position errors between the read-only heads and their associated servo heads to a servo head address deriving unit (24), which corrects track addresses of items of servo information read by the read-only heads and transmits the corrected track addresses to a servo pattern generator (9) to make the servo heads write the corrected address. This shortens the time needed for writing servo patterns to magnet disks with high density and high accuracy.

摘要： A method for obtaining relative positional relationships between a read-only head for reading data from an original disk and servo heads on each surface of magnetic disks (copy disks), in a magnetic data writing apparatus (disk servo writer) that stacks copy disks and an original disk to rotate the disks unitarily. The apparatus includes a rotary positioner on the periphery of the copy disks and a read-only disk, stacking the read-only head and servo heads rotatably. The apparatus causes the servo heads simultaneously to write servo data to respective assigned track ranges. The method includes stacking calibration disks storing servo data in place of the copy disks in a coaxial relation with the read-only head, in advance of writing magnetic data to the copy disks. Using the calibration disks, relative positional relationships are obtained as between the address that the read-only head reads out from the original disk and the addresses that servo heads read out from calibration disks at the same time that the read-only head reads out the address thereof.

摘要： A management system of a storage apparatus, which exercises control so as to arrange data in a storage device of a certain tier of multiple tiers, carries out a first tier definition process (a process for distributing multiple storage devices to multiple tiers based on respective storage device types of the multiple storage devices and type/tier information that denotes the corresponding relationship between multiple storage device types and multiple tiers). Subsequent to the first tier definition process, the management system acquires performance information denoting the performance of a storage device for each of the multiple storage devices. The management system carries out a second tier definition process (a process for distributing the multiple storage devices to the multiple tiers based on the performance information of multiple storage devices such that two or more storage devices of similar performance are distributed to the same tier).
