SCANNING REPRODUCING APPARATUS FOR DISC TYPE VIDEO RECORDS |
摘要 |
<p>A signal reproducing system particularly adapted to be used with a high frequency signal such as a video signal. In this system, a record medium formed with a guide groove having an uneven pattern formed on an inner wall thereof with projections of the uneven pattern being located at intervals corresponding to time-axis changes in a time-axis modulated signal is scanned by a scanning member. The record medium is pressed by the scanning member along the guide groove, the scanning member being supported by an essentially elastic material. A change in the inclination angle of the scanning member with respect to the record medium occurs when a portion of the tip end of the scanning member engages with or disengages from the projections. The change in inclination angle is detected by a mechanicalelectrical transducing element arranged in contact with the scanning member as an electrical signal to produce a reproduced signal.</p> |
