    摘要: Apparatus is disclosed for providing an optical system which drives beam collecting lens by piezo device, for focusing the beam which moves according to the rotation of reflection mirror for using beam scanning that scans the laser beam on the surface of optical magnetic tape to be always set on the surface of the tape. An optical magnetic recording system modulates an image signal and converts the modulated signal to laser signal, and drives beam collecting lens (object lens) that collects the laser data by the synchronizing signal of the image signal, so as to allow optical magnetic recording on the tape surface. An optical recording system for recording by helical scanning the collected beam of the beam collecting lens on the tape surface using polysurface rotary mirror. An optical recording and playback system picks up optically recorded data on a optical magnetic tape using a contact sensor. A magnetic recording data pick-up device having a Hall sensor array, detects optical recording data on the surface of the optical magnetic tape by approaching the surface thereof, an accumulator and a shift array for accumulating and shifting the signal from the Hall sensor array. A magnetic recording data read control circuit which controls magnetic recording pick-up device by control data recorded according to main data.
