  • Publication number: 20060187568
    Abstract: Methods in accordance with embodiments of the present invention can be applied to self-servo write a disk in a hard disk drive device having a ramp positioned near an outer diameter of the disk. In one such embodiment, a first user track can be assigned based on an acquire track such that a conservative buffer exists between the first user track and the acquire track, thereby avoiding damage to the disk surface. A first portion of a data region can be defined between the first user track and a track near an inner diameter. A second portion of the data region can be defined between a track near the ramp, such as the acquire track, and the first user track. Servo tracks can be self-servo written across the first and second portions, and critical system information can subsequently be written to the first portion.

  • Patent number: 6600625
    Abstract: A disk drive includes a storage disk, a head stack assembly and a fluid deflector. The head stack assembly includes a transducer assembly. The fluid deflector includes a deflector finger that deflects turbulent fluid flow away from the transducer assembly. The fluid deflector can include one or more landing pads that inhibit the slider from landing on the storage disk. The deflector finger can include a side that remains in close proximity to the slider during operation of the disk drive.
