Control apparatus for a recording/playback system using an endless recording medium |
摘要 |
A control apparatus for a recording/playback system using an endless recording medium having a position detecting mark attached thereto and driven at a given speed to move along an endless loop, wherein the position detecting mark is detected as the recording medium is driven and a mark position signal generated to indicate each passage of the mark passed a predetermined point in the endless loop. Recording or playback operation is controlled based on the time between detection of successive mark position signals which is indicative of the one-cycle length of the recording medium. The one-cycle length of the endless recording medium is stored as data which may be changed upon changing of the tape length and/or the tape speed. Once the one-cycle length data is stored, automatic recording may be started from any position on the endless recording medium at any time.
