Picture storage device

Abstract

Abstract PURPOSE:To successively read data from data to correspond to a desired time by providing a writing processing part which repeats writing and reading processing part to successively execute reading according to a writing order from a designated track in an optical disk. CONSTITUTION:Since a writing head driving part 3 executes the writing with being endless, the program of a station, which is turned by a television tuner 1 is continuously recorded to a magneto-optical disk 4. Next, by the operation of an operating part, a reading pick-up driving part 5 starts the reading of the disk 4 from the designated track. After the reading of the outer-most circumference track is finished, the driving part 5 searches the track in the inner-most circumference and starts the reading again. During the search, a reading control circuit 32 reads the data in a RAM 31. When the display of a televisions set 7 is executed by switching the output signal of a demodulating circuit 6, the picture data at a time, which goes back only by the time of correspond to the designated track, can be displayed on the television set 7.
