Estimating the term…
An apparatus for a disk drive having at least one disk mounted in a housing having a controlled environment defined by the housing. Such a disk drive generally includes, within the controlled environment, one or more transducers for reading information from and writing information to the disk, and at least one actuator for selectively positioning the transducers with respect to the disks. Each actuator includes at least one magnet for providing a magnetic field and an actuator coil, mounted on the actuator, arranged so that a current in said coil creates a force to pivot the actuator. The apparatus comprises a magnet shield encasing each such magnet for preventing matter, generated during the decomposition of said magnet over a period of time, from interfering with the operation of the disk drive.
A disk drive, comprising:
A disk drive including a housing having a base, and a first cover, the base and first cover defining a first controlled environment when engaged, comprising:
An apparatus for a disk drive having a housing comprising a first cover coupled to a base defining a first controlled environment isolated from ambient atmospheric conditions and pressures, the disk drive including a data storage medium, a transducer for reading information from and writing information to the data storage medium, and an actuator for selectively positioning the transducer with respect to the data storage medium, all included within said first controlled environment, the actuator including a magnet coupled to a magnet support structure, for providing a magnetic field and a voice coil assembly mounted on the actuator, comprising a magnet shield cover coupled to said magnet support structure and defining a second controlled environment, isolated within said first controlled environment, encasing said magnet.
