摘要： Embodiments of the present invention provide a head stack assembly and a manufacturing method thereof in which manufacturing costs as a multi-disc magnetic device are reduced by increasing the yield and reducing inventory of magnetic heads which can be assembled to the head stack assembly. According to one embodiment, a head stack assembly and a manufacturing method thereof includes plural actuator arms to which magnetic heads are assembled through suspensions. The tolerance of the core width or the write element width of the magnetic heads assembled to inside actuator arms of the plural actuator arms is set to be narrower than the tolerance of the core width or the write element width of the magnetic heads assembled to the outside actuator arms.

摘要： A method for manufacturing a hard-disk drive (HDD). The method for manufacturing a HDD includes writing servo tracks, and writing servo tracks into the HDD using a calculated control target value of a calculated servo pattern overlap amount. Writing servo tracks includes a first, second, third and fourth operation. The first operation includes: producing a first control equation for obtaining a servo pattern overlap amount; and, converting a root-mean-square error (RMSE) into a probability distribution. The second operation includes calculating a second control target value that results in an increased product yield, from the RMSE probability distribution. The third operation includes producing a second control equation for obtaining a calculated servo pattern overlap amount, by assigning the second control target value into the first control equation. The fourth operation includes calculating the calculated control target value using the second control equation and the magnetic-recording-head characteristic value.

摘要： Embodiments in accordance with the present invention erase a desired area on a recording surface of disk or disk drive apparatus. According to an embodiment, a hard disk drive (HDD) performs erase on a recording surface by moving a head element unit at one-half a servo track pitch with reference to a servo address. Before actual erase is started on the recording surface, the HDD generates a management table configured based on servo addresses from a management table configured based on data tracks. At an erase process, the HDD sets parameters in accordance with the zone and skips a management area with reference to this management table based on the servo addresses.

摘要： A drive roller for use in a conveyor, comprising rotary shafts supported in respective bearings, the respective rotary shafts being provided at the respective ends of a core member and one of the rotary shafts being connected to a drive source. The core member is a hollow- or solid-cylindrical one and has provided thereon and fastened at the respective end portions thereof a tubular inflatable member having at least one inner cord layer in which the cords are laid with a predetermined angle, one end of which inflatable member is fastened to one end portion of the core member while the other end of the inflatable member is folded back inwardly and fastened to the other end portion of the core member, thus a sealed space being defined between the inflatable member and the outer surface of the core member. A fluid passage is formed in the core member to supply and discharge the fluid to and from the sealed space to inflate and deflate the inflatable member, the inflatable member when inflated having a cylindrical outer surface. A to-be-conveyed object is supported and driven only on the outer surface of the inflatable member when inflated.
