ラツク記憶回路。 In an electronic still camera that records a plurality of still images on concentric signal tracks of a magnetic disk, there is a recording/recording system that determines whether each signal track has been recorded or not, based on the reproduction signal from the magnetic head 2.
A non-recording discrimination circuit 4, a main memory 6 for storing the discrimination result for each track, an auxiliary memory 7 for storing the track number of the signal track for which recording/non-recording has been determined, and a recording/non-recording discrimination circuit. 4 and both memories 6 and 7, and a discrimination cancellation button 8 for instructing to stop the discrimination operation. The first control unit instructs the determination and writing of data to both memories 6 and 7 accordingly, and the determination cancellation button 8.
Recording/non-recording discrimination circuit 4 based on the operation signal from
A second control section is provided which stops the operation of the track and also refers to the contents of the auxiliary memory 7 and writes a signal indicating non-recording to the recording area of the main memory 6 corresponding to all the tracks following the memory contents. An unrecorded track storage circuit for an electronic still camera, characterized in that:
