A still video device in which image signals corresponding to one frame are divided into a plurality of parts and recorded on a plurality of tracks on a magnetic disk. On a track on which an image signal forming the same frame as the other track, the same lead track number is recorded in an ID code recording area of the track. In a recording operation, the ID code is decoded, so that the lead track number is stored in a memory. When a lead track number of a track which is reproduced is coincident with the lead track number stored in the memory, the image signal of the track is stored in a predetermined area of the memory in accordance with a composing frame number. By repeating such an storing operation, all of the image signals forming one frame are reproduced. Then, the image signals are read out from the memory in a predetermined order so that the reproduced image is outputted to a display device. |

DETAILED DESCRIPTION Therefore, an object of the present invention is to provide a still video device, by which an image signal corresponding to one frame can be recorded on a plurality of recording areas even if a plurality of consecutive blank tracks do not exist, and the recording areas are reproduced so that one frame is obtained.
According to the present invention, there is provided a still image recording device comprising a recording medium, a dividing means, a selecting means and a recording means.
The recording medium has a plurality of recording areas in which an image signal recording part and an ID code recording part are provided, respectively.
An image signal is recorded in the image signal recording part, and an ID code including a date is recorded in the ID code recording part.
The dividing means divides the image signal corresponding to one frame into a plurality of parts.
The selecting means selects a blank recording area in which no signal is recorded, from the recording areas.
The recording means records the divided parts of the image signal in the image signal recording part of the blank recording area, respectively.
The recording means records frame-identifying-information in the ID code recording part of the recording area in which the image signal is recorded by the recording means.
The divided parts of the image signal corresponding to the one frame, recorded by the recording means, is identified by the frame-identifying-information.
Further, according to the present invention, there is provided a still video device in which a recording medium is mounted, the device comprising dividing means, divided-parts recording means, frame-identifying-information recording means, divided-parts information recording means and reproducing means.
The recording medium has a plurality of recording areas in which an image signal recording part and an ID code recording part are provided.
An image signal is recorded in the image signal recording part.
An ID code including a date is recorded in the ID code recording part
