Abstract:
An apparatus reproducing signals recorded on a tape in slow reproduction, wherein the signals are compressed to digital data and recorded in predetermined M tracks (M&gE;1) on a tape with helical scan in the unit of a page consisting of N frames (N&gE;1), and position data representing position in the M tracks are added to the digital data on recording at predetermined positions in the M tracks, comprising:a reproduction processor which converts signals reproduced from a magnetic tape to compressed digital data; a decoder which decodes the compressed digital data reproduced by said reproduction processor to digital data; a first storage device which stores the data decoded by said decoder in the unit of N frames; a second storage device which delays data received from said first storage device by a time of a frame; a position detector which detects the position data in the data reproduced by said reproduction processor to determine which reproduction position is reproduced by said reproduction processor in an area where the data in a page are recorded; a read controller which receives the determined reproduction position from said position detector during a frame period and generates a control signal according to the determined reproduction position observed during a frame period, the control signal being determined to make output time of a frame even; a memory controller which controls reading from said first storage device according to the control signal received from said read controller; and a switch which selects data to be output between data received from said first storage device and data received from said second storage device according to the control signal received from said read controller.
