Abstract
An apparatus comprising a slider is configured for heat-assisted magnetic recording. The slider comprises a media-facing surface. One or more reader elements are positioned in a reader region of the slider, and the one or more reader elements have an average first elevation at the media-facing surface. One or more writer elements are positioned in a writer region of the slider, and the one or more writer elements have an average second elevation at the media-facing surface. The average second elevation is less than the average first elevation.
Claims20
An apparatus, comprising:
- a slider configured for heat-assisted magnetic recording and comprising a media-facing surface;
- one or more reader elements positioned in a reader region of the slider, the one or more reader elements having a passive average first elevation at the media-facing surface;
- and
- one or more writer elements positioned in a writer region of the slider, the one or more writer elements having a passive average second elevation at the media-facing surface, the passive average second elevation being less than the passive average first elevation.
An apparatus, comprising:
- a slider configured for heat-assisted magnetic recording and comprising a media-facing surface;
- a reader positioned in a reader region of the slider, the reader region comprising a dielectric material at the media-facing surface at a passive first elevation;
- and
- a writer and a near-field transducer positioned in a writer region of the slider, the writer region comprising the dielectric material at the media-facing surface at a passive second elevation, the passive second elevation being less than the passive first elevation.
An apparatus, comprising:
- a slider configured for heat-assisted magnetic recording;
- one or more reader elements positioned in a reader region of the slider, the reader region extending across the crosstrack dimension of the slider and configured to have a first passive fly-height with respect to a medium;
- and
- one or more writer elements positioned in a writer region of the slider, the writer region extending across the crosstrack dimension of the slider and configured to have a second passive fly-height with respect to the medium, the second passive fly-height being greater than the first passive fly-height.
