摘要: The laser pulse readout scheme is advantageous in reading thermal super resolution disks, but the light modulation on the RF signal confuses the detection channel. A synchronous trigger detection scheme, using the pulse laser trigger signal to pick up the desired signal, is proposed to suppress the adverse effects of the light modulation. A 5-dB increase of the signal on an magneto-optical super resolution center aperture detection disk by the synchronous detection system was demonstrated experimentally.
