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.
