ABSTRACT:
A device for reproducing a picture without noises in slow and/or high speed search modes of operation and a method therefor. The device records an address indicative of tape position on a control track of a video tape, the address being comprised of a single address block; jumps over a certain number of the addresses when operating in the slow mode of operation, to perform accurate tracking and thereafter reading picture data, records the picture data in a memory, and reproduces the picture data repeatedly during jumping over the certain number of addresses; switches successively the heads substantially at 1/4 and 3/4 positions of a full control tracking time when operating in the high speed search mode of operation, thereby recording the picture data in the memory so as to form a complete picture of one frame to be reproduced.
