A recording and reproduction apparatus for recording signals on a recording medium or reproducing signals recorded on the recording medium, which is so arranged that, with acceleration detectors being provided for detecting accelerations of the apparatus by vibrations or impacts applied from outside, signals from the acceleration detectors are applied to control section for stabilization of the control system and also, for proper treatment upon application of excessively large external vibrations or impacts, with consequent improvements of reliability and stability of the apparatus.

A recording and reproduction apparatus which includes means such that a light beam which converged and projected onto a recording medium is displaceable in a direction parallel to a surface of the recording medium and perpendicular to a track thereon so as to record signals on the track or to reprod

A recording and reproduction apparatus which includes means such that a light beam which converged and projected onto a recording medium is displaceable in a direction parallel to a surface of the recording medium and perpendicular to a track thereon so as to record signals on the track or to reproduce signals recorded on the recording medium, said recording and reproduction apparatus comprising an acceleration detecting means for detecting acceleration of the apparatus due to vibrations or impacts externally applied thereto and for supplying an output signal corresponding thereto, an abnormal state detecting means for detecting that a magnitude of the vibrations or impacts applied to the apparatus has exceeded a predetermined value based on said output signal from said acceleration detecting means and for supplying an output signal corresponding thereto, and a means for inhibiting recording in accordance with said output signal from said abnormal state detecting means.
