    Abstract: In an insert recording system for a video signal, a tape is recorded with a video signal along tracks formed obliquely with respect to the longitudinal direction of the tape, a part of recorded tracks is erased, and a different or new video signal is recorded onto the erased part. The insert recording system comprises one or a plurality of video heads for recording the different or new video signal onto the erased part of the tape, one or a plurality of flying erase heads mounted on a rotary body provided with the one or a plurality of video heads, at a position leading the video head by an angle .theta. (in radians) with respect to the rotating direction of the video head, where the flying erase head has a track width wider than the track width of the video head, an erasing current generating circuit for generating an erasing current, a first control circuit for controlling supply of the erasing current to the flying erase head, and a second control circuit for controlling supply of the different or new video signal to video head.

    Abstract: A storage device including an initial data storage area storing initial data, an updated data storage area storing updated data corresponding to the initial data, and a designation area designating either the initial data storage area or the updated data storage area to be readout. A storage control device comprises a write writing data in the updated data storage area, a re-write unit re-writing the designation area in which information for reading the initial data storage area is set in the initial stage into the setting of reading the updated data storage area when writing into the updated data storage area occurs, an initializing unit re-writing the information in the designation area to the setting of reading of the initial data, and a selection unit selecting to read either the initial data storage area or the updated data storage area when reading the data.

    Abstract: A sound signal recorded in a memory synchronously with a low-frequency clock signal is read out with the low-frequency clock signal to reproduce a normal sound, thereby enabling checking of the sound signal recorded in the memory. For recording in a recording medium, the sound signal is read out with a high-frequency clock signal to effect time axis compression. By designating an address to start writing, a sound signal can be written starting with any address thereby facilitating editing. An analog sound signal previously recorded on a magnetic recording medium is time axis expanded by a time axis expansion device and then outputted from a sound output device, and the analog sound signal is hybridized with another analog sound signal inputted from a microphone, time axis compressed by a time axis conversion device, and recorded on the magnetic recording device.
