Title: Information recording optical system
Inventor: KATAOKA KEIJI
IPC: G11B7/1398
Filed: 1985-03-29
Abstract: PURPOSE:To execute plural optical scans having no distortion by a single optical scanner by placing a cylindrical lens in front of a recording material, when plural beams of laser light are made incident on a single optical scanner and plural records are executed by the reflected light. CONSTITUTION:A cylindrical lens 12 is placed in front of recording materials 9, 10. Laser light from laser light sources 19, 20 is brought to optical modulation by optical modulators 17, 18, made elliptical by one direction beam magnifiers 15, 16 and made incident on an optical scanner at each dirrerent angle. The reflected light is separated by mirrors 13, 14 and executes an optical scan to the recording materials 9, 10. In that case, for instance, when a screen is in an A position, unless the cylindrical lens 12 exists, the laser light is irradiated on a C position, but when the lens 12 is provided, the distortion is corrected to a D position and also, when the screen is placed at a Q position, the distortion is corrected completely. Therefore, plural optical scans having no distortion can be executed by a single optical scanner.
