Abstract: A fast access bulk storage device, using magnetic tape, for storage and retrieval of data includes a page-counting circuit which samples and stores actual page location, by detecting translucent portions on the tape denoting beginning of page, and constantly compares it to any given page address entered into the system, and a data buffer stage, comprised of a continuous loop of magnetic tape of approximately one page length, which provides for temporary storage of data while the main storage device is being accessed.
