Title: Optical scanning device
Inventor: MORIMOTO YASUAKI
IPC: G11B13/04
Filed: 1995-06-29
Abstract: A system for reducing crosstalk in an optical scanning device for recording and reading optical data and magneto-optical data arranged in tracks of a recording medium includes a source for providing two light beams which are scanned along the tracks. The light beams are polarized in two polarization directions, are focused onto one of the tracks and are separated by a predetermined distance along the direction of the tracks, when incident on the tracks. Reflected light from the recording medium is focused onto first and second pairs of sensors. The difference of the signals from the first pair of sensors is compared with a delayed version of the difference of the signals from the second pair of sensors to provide a further signal representing magneto-optically recorded data. Signals from a first sensor of each pair of sensors may be summed to detect optically recorded data. One of the sensors of one pair of sensors may be realized as a four quadrant detector to provide conventional tracking and focusing error signals.
