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： A servo write method for a hard-disk drive. The method includes generating, with an input of characteristics of a magnetic-recording head and a magnetic-recording disk which are incorporated into the hard-disk drive, a yield prediction model from a correlation between yields of the hard-disk drive, and characteristics of the magnetic-recording head and the magnetic-recording disk of the hard-disk drive in a process. The method also includes predicting a yield which is obtained when each magnetic-recording head is used as a position control head, selecting as the position control head a magnetic-recording head that has a highest predicted yield, and writing a servo signal.

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： In an optical transmission tube comprising a tubular cladding and a core within the cladding having a higher index of refraction than the cladding, a strip-shaped reflecting layer is longitudinally extended between the cladding and the core. Light passing through the core is reflected and scattered by the reflecting layer to emerge from the tube through an area of the outer surface of the cladding opposed to the reflecting layer. The optical transmission tube is prepared by dispersing scattering particles in a monomer solution; filling a tubular cladding with the monomer solution; resting the cladding horizontally for allowing the scattering particles to settle on a lower inner surface of the cladding; and thereafter, causing the monomer solution to polymerize and solidify within the cladding.
