Title: Optical pickup of optical information recording and reproducing device
Inventor: GOTO HIROSHI
IPC: G11B7/125
Filed: 1993-08-20
Abstract: PURPOSE:To stabilize the operation by compensating the output of a photodetector for monitoring a light quantity by means of the output of a front photodetector and performing the power control of the semiconductor laser. CONSTITUTION:When the polarization plane of the transmitted light from a semiconductor laser 1 is rotated due to a temp. change, an S polarization component appears, is reflected by a beam splitter 3, converged by a convex lens 22 and received by a second photodetector 23. The output of a photodetector for monitoring a light quantity in the laser 1 is compensated by the output of the element 23 and power control is automatically performed by means of a semiconductor laser driver 11 including an APC circuit. Since the P polarization component decreases as much as the S polarization component increases due to temp., the output of the photodetector for monitoring a light quantity is compensated by detecting the S polarization component. Consequently, even when the polarization plane of the transmitted light from the laser 1 is rotated due to a temp., the light power of a spot on a disk 6 is controlled to be a constant value and exact recording/reproducing operation is enabled.
