    摘要: Embodiments of the invention provide a manufacturing method for a disk drive which allows highly accurate recording of servo data without substituting the internal gas of the disk drive, and such a magnetic disk drive and servo track writer. In one embodiment, a disk, a magnetic head slider with a head for writing data onto and reading out data from the disk, a suspension for retaining the magnetic head slider, an arm for supporting the suspension, and a driving section for driving the arm are stored into an enclosure. When a servo track write operation is conducted, the enclosure interior is depressurized to an atmospheric pressure lower than normal pressure and then servo data is recorded on the disk.

    摘要: A method for testing a mold structure including magnetically transferring a magnetic signal according to a concavo-convex pattern for a servo area in a mold structure to a perpendicular magnetic recording medium; electrically reproducing ≧50 tracks of the magnetic signal of servo data transferred onto the perpendicular magnetic recording medium using a magnetic head to obtain a reproduction signal; and calculating a pattern drawing accuracy radially from the reproduction signal to evaluate a performance of the mold structure including a disc-shaped base material; and the concavo-convex pattern for the servo area and a concavo-convex pattern for a data area formed on a base material surface following a desired design pattern. The concavo-convex patterns for the servo area are aligned in the radial direction of the base material, and the concavo-convex pattern for the data area are aligned in the circumferential direction between the concavo-convex patterns for the servo area.
