Abstract
Embodiments disclosed herein generally relate to a magnetic recording device including slider, a magnetic head assembly and a laser diode having a photodiode integrated therein. The photodiode and the laser diode are both fabricated on a structure. Having the integrated laser diode and photodiode reduces the cost relating to fabricating individual, discrete photodiode and assembling the individual, discrete photodiode on the magnetic recording device.
