The present invention is concerned with a recording medium wherein, in a recording medium in which the information may be regenerated optically, a track is pre-recorded or pre-formatted by being deviated along the track width with a signal which the baseband signal of a read-only information signal freed of high-frequency components. The present invention is also concerned with a recording apparatus for forming a track of an optical recording medium from which an information can be reproduced optically, wherein the apparatus includes a deviating device for deviating a track-forming recording beam along the width of the track of the optical recording medium, a deviation control signal generating device for generating deviation control baseband signals for controlling the deviation device, and a low-pass filter for eliminating the high-frequency components of the deviation control baseband signals.
An information recording apparatus for forming a track on an optical recording medium from which recorded information is read out by optical means, said apparatus comprising
An information recording apparatus for forming a track on an optical recording medium from which recorded information is read out through optical means having a high cut-off frequency of at least 1.4 MHz. so that frequencies of the read out recorded information above 1.4 MHz. are cut of, said apparatus comprising
