Abstract
Information recording/reproducing apparatus such as a VTR records and reproduces information such as image information in and from a recording medium such as a magnetic tape. The apparatus has a tape feeding device which can feed the tape selectively at a first speed which is the same as the tape speed during recording and a second speed which is, for example, 1/2 the first speed. In a slow-speed reproducing mode of the apparatus, the tape is fed intermittently such that a phase in which the tape is fed at the second speed and a phase in which the tape is held still appear alternately. During the running of the tape at the low second speed, a predetermined region, e.g. a track, is traced by reproducing heads a plurality of times in an overlapping manner, so that fractions of data stored in the track are reproduced by the reproducing heads. These data fractions are reassembled within a memory based on address data contained in the reproduced data fractions, so that a video output is synthesized in the memory. With this arrangement, data can be obtained from almost the entire area of each track, so that slow-speed reproduction can be conducted with improved quality of the reproduced image.
