Abstract
An apparatus comprises a heat-assisted magnetic recording drive which includes an enclosure having a base and a cover. The drive includes a magnetic recording disk and a head gimbal assembly proximate one of the base and the cover. The HGA supports a slider assembly comprising a laser diode unit. The LDU projects away from the HGA towards one of the base and the cover. An arcuate channel is provided in one of the base and the cover and dimensioned to receive a distal portion of the LDU. The channel has a length that accommodates the distal portion of the LDU along a stroke of the HGA.
Claims20
An apparatus, comprising:
- a heat-assisted magnetic recording drive, comprising:
- an enclosure comprising a base and a cover;
- a magnetic recording disk;
- a first head gimbal assembly (HGA) proximate the cover and supporting a first slider assembly comprising a first laser diode unit (LDU), the first LDU projecting away from the first HGA towards the cover;
- a second HGA proximate the base and supporting a second slider assembly comprising a second LDU, the second LDU projecting away from the second HGA towards the base;
- a first arcuate channel provided in the cover and dimensioned to receive a distal portion of the first LDU, the first channel having a length that accommodates the distal portion of the first LDU along a stroke of the first HGA;
- and
- a second arcuate channel provided in the base and dimensioned to receive a distal portion of the second LDU, the second channel having a length that accommodates the distal portion of the second LDU along a stroke of the second HGA.
An apparatus, comprising:
- a heat-assisted magnetic recording drive, comprising:
- an enclosure comprising a base and a cover;
- a magnetic recording disk;
- at least one head gimbal assembly (HGA) proximate one of the base and the cover, the HGA comprising:
- a load beam having a first surface, a second surface opposing the first surface, and an aperture;
- a suspension connected to the second surface of the load beam and configured to support a slider assembly comprising a laser diode unit (LDU), the LDU extending through the aperture of the load beam and projecting away from the first surface toward one of the base and the cover;
- and
- an arcuate channel provided in one of the base and the cover, the channel dimensioned to receive a distal portion of the LDU and having a length that accommodates the distal portion of the LDU along a stroke of the HGA.
