Abstract: PURPOSE:To provide a picture recording and reproducing device capable of being compatible with high-speed access and long-time recording relating to picture and sound information and also being operated without making a user conscious of device constitution. CONSTITUTION:This device is constituted of the medium and drive 8 of a tape system of a low bit cost though an access speed is slow, the medium and drive 5 of the disk system of a relatively small capacity though the access speed is fast, the compression and expansion 4 and 7 of data, semiconductor memories 3 and 6 for absorbing the access time of the drives, a switcher 10 for switching reproducing information from the drives of the two systems and performing the smooth transition of picture data and a controller for controlling the operations of this constitution. Since the cost of the medium is suppressed low in cost as much as possible and the picture recording and reproducing device whose access time is short can be realized, the ratio of performance against a price can be improved. Also, the transfer to the information from both storage means and the transfer from a retrieval screen to a viewing screen, etc., which are difficult to be realized just by simply combining components can be smoothly performed.
