Abstract
In a recording operation, video data is written to a single port memory at a periodic interval, and the video data is read from the memory between points in time when the video data is written. The read video data is recorded on a recording medium. During a reproducing operation, reproduced video data is written in the single port memory, and the reproduced video data is read from the memory at a periodic interval. Further reproduced video data is written to the memory between points in time when the reproduced video data is read. In backward reproduction, reproduced video data is read in an order opposite to that in which it was written.
