An apparatus including a heat sink layer and a magnetic recording layer over the heat sink layer. In addition, a thermochromic layer is over the heat sink layer, wherein the thermochromic layer includes a first optical absorbance at a first temperature and a second optical absorbance at a second temperature.

Apparatuses and methods for absorbing optical energy

Provided herein is an apparatus including a head over-coat and a depleted region in the head over-coat. A media over-coat is deposited in the depleted region. A near field transducer is adjacent to the head over-coat, wherein the near field transducer combusts the deposited media over-coat.

Selective heat-assisted removal of head over-coat and media over-coat

Provided herein is an apparatus including a substrate and a magnetic recording layer over the substrate. In addition, a thermochromic layer is over the substrate, wherein the thermochromic layer includes a first optical absorbance at a first temperature and a second optical absorbance at a second temperature.
