Abstract
A recording/reproducing apparatus by which optimum playback pictures can be produced eve in case of parallel recording/reproduction. A storage unit 123 transiently stores video signals obtained from an overwrite type disc-shaped recording medium 102. A signal processing unit 122 decodes video signals stored in the storage unit 123. A holding unit 124 holds video signals decoded by the signal decoding unit 122. A control unit 101 performs control of the entire apparatus and also performs control for address management and data transfer of the disc-shaped recording medium 102 so that, if the apparatus is set to a mode of performing a playback operation while the recording operation is going on, the storage means 123 stores plural fields of the video signals and the holding unit 124 interpolates the video signals.
