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 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 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： A high yield in a manufacture of an HDD having a high recording density and using a patterned medium by a trench-like or a dot-like pattern is realized. In this HDD manufacturing method, a magnetic field size (writing and reading) of a head in a head manufacturing process is measured in a head unit inspection process. According to the result of the measurement, the head is classified into a plurality of groups in a head classifying process. In a patterned medium manufacturing process, a plurality of types of the patterned media which are designed so as to correspond to the classified head groups are manufactured. In an HDD assembly process, the HDD is manufactured by combining the plurality of head groups and the plurality of patterned media following a predetermined rule.

摘要： Techniques for performing metrology on magnetic media disk formations that are arranged in curvilinear patterns are disclosed. Small integrated test patterns having rectangular periodicity are integrated among the concentric circles of patterned media formations. The test patterns cover only very small areas of the disk so as to not significantly affect disk capacity. The periodicity of the test patterns allows their formations to be more readily measured by metrology technology than those having a curvilinear periodicity.
