A dynamically paged non-volatile random access video store has a random access memory integrated with a disk drive. The random access memory provides realtime access for recording and playing back video from and to a video source. The disk drive provides a non-volatile backup for the random access memory by transferring data between the disk drive and random access memory automatically, or by command, on a non-realtime basis. The video data accesses and transfers are handled by a microprocessor that interfaces with a controller by which an operator inputs instructions. Multiple channels are accommodated via a channel interface, also controlled by the microprocessor, between external video devices and the random access memory. The disk drive stores a plurality of pages of video data, each page corresponding to the capacity of the random access memory.
