ABSTRACT:
A rotary video head type information recording/reproducing apparatus in which a video tape runs while being in contact with a stationary head at the time of fast-feeding/rewinding of the video tape. In recording/reproducing operation of the information recording/reproducing apparatus, a one-scene picture is extracted at intervals of a predetermined period from a picture signal and the extracted picture is recorded on the video tape by the stationary head in synchronism with the picture signal. When it is desired to perform a picture search, a still picture which changes at intervals of the predetermined period can be reproduced on a picture screen of a display only by performing the fast-feeding/rewinding operation. Accordingly, an operator can perform search for a desired picture at a high speed by referring to the timing of change of the still picture actually displayed on the picture screen.
