Abstract
A skinned, foam core E-block assembly for a disk system for supporting a plurality of head arrays to write data to and/or retrieve data from tracks of a media disk. The E-block assembly is formed of a foam core material with a non-porous stressed skin that matches or exceeds the performance of currently used materials, at a lower cost. The foam may be ceramic, metallic, or polymeric. The skin is non-porous and may also be ceramic, metallic, or polymeric.
Claims10
An E-block assembly for supporting a plurality of head assemblies of a disk drive system to write data to and/or retrieve data from tracks of a media disk, the E-block assembly comprising:
- an actuator coil;
- a casing injection molded around the coil, the casing being formed of an electrically non-conductive polymeric material;
- and;
- a unitary E-block rigidly mounted to the casing and constructed of a foam core with a non-porous stressed skin, the E-block having a pivoting portion having an axis and a plurality of arms extending from the pivoting portion normal to the axis, each arm being capable of supporting at least one head assembly at a free end thereof, the arms being uniformly constructed of a foam core completely surrounded by a non-porous stressed skin.
In a disk drive system for writing data to and retrieving data from tracks of a media disk, the disk drive system including a plurality of head assemblies for recording data to and/or retrieving data from tracks of a media disk, an E-block assembly comprising:
- a unitary E-block rigidly mounted to the casing and constructed of a foam core with a non-porous stressed skin, the E-block having a pivoting portion having an axis and a plurality of arms extending from the pivoting portion normal to the axis, each arm being capable of supporting at least one head assembly at a free end thereof, the arms being uniformly constructed of a foam core completely surrounded by a non-porous stressed skin.
