CPC G11B 5/012 (2013.01) [G11B 2005/0021 (2013.01)] | 20 Claims |
1. A circuitry comprising:
a sensor of a first circuit configured to receive as input an optical signal of a laser of a storage device and output a first voltage indicative of the optical signal;
an amplifier of the first circuit configured to amplify the first voltage to produce an amplified first voltage indicative of a mode hop event, the amplified first voltage trailing the optical signal by a first response time of a first frequency response of the first circuit;
a second circuit coupled in series with the first circuit and configured to receive the amplified first voltage, the second circuit operating according to a second frequency response that is an inverse of the first frequency response; and
wherein the circuitry is configured to generate, based at least on the amplified first voltage adjusted by the second frequency response, a second voltage indicative of the mode hop event, the second voltage generated within a second response time that is shorter than the first response time.
