    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: 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 light transmission tube includes a tubular clad and a core section having a higher refractive index than that of the tubular clad. A belt-like reflecting layer is formed between the tubular clad and the core section, extending in the longitudinal direction of the tubular clad, in a manner such that a light passing through the core section is reflected and scatterred by the reflecting layer and then emitted from an outer surface area of the tubular clad, which outer surface area is located opposite to one side of the tubular clad where the reflecting layer has been formed. Further, the reflecting layer may be so formed that a light is allowed to be emitted in a plurality of directions. Moreover, the belt-like reflecting layer may be formed into a spiral configuration. The width of the belt-like reflecting layer may be changed in the longitudinal direction of the light transmission tube. The tubular clad is allowed to have a non-circular cross section. The clad formation material may contain an ultraviolet light shielding material or an ultraviolet light absorbing material.
