A Data Storage Pack is disclosed which contains in the same housing (a) a plurality of analog data storage units such as video tape arranged in a two dimensional matrix and (b) a RAM data storage unit. The data in RAM identifies and locates the video data by tape unit in the matrix and location on the tape. The RAM memory units of a plurality of these packs are connected to a central processing unit to permit merger of the digital identification data and thus more efficient use of the RAM space. Pairs of these data storage packs may be stacked spaced from one another. A robot arm and a tape player positioned between the stacks are under control of the RAM data to select and play the desired analog information from the appropriate portion of the appropriate tape in the matrix involved. There are disclosed an advantageous multiple tape cassette arrangement, an advantageous electric motor arrangement for designing and selecting a disk when such is employed as the analog data unit in said matrix, an advantageous robot arm arrangement, and an advantageous data interleaving system for the analog tape. |

DETAILED DESCRIPTION OF THE INVENTION The current invention of information processing system comprises a CPU (central processing unit), a plural number of digital communication controllers, a plural number of analog communication controllers, a house of digital/analog memory storage and an analog tape buffer pool.
The digital communication controller interfaces between CPU and digital memory, CRT, printer and other digital terminals.
The analog communication controller interfaces between analog terminals and the analog read/write heads.
Analog terminals are such as TV, audio receiver, video camera, speaker, microphone, satellite receiver, video cassette recorder, etc.
There are three system block diagrams to be discussed: FIG.
1, FIG.
22 and FIG.
23.
FIG.
1 is the simplified version.
After the components being discribed, FIG.
22 summarizes the relation of those components.
FIG.
23 is the system flow diagram to emphasize the data flow.
SIMPLIFIED BLOCK DIAGRAM OF CERTAIN BASIC COMPONENT (FIG.
1) FIG.
1 is a simplified block diagram to show basic concept of the apparatus.
The digital application data is entered via digital monitor.
Under the instructions of software, the central processing unit (CPU) then tried to find the record related to said digital application data by searching the random access memory (RAM) portion of a memory pack.
After the record being found, the digital portion of said record from RAM is displayed back to digital monitor.
The location data of the analog portion of said record (also from RAM) then is sent to a robot to pick up a cassette (tape or disk) from a N by M cassette matrix.
The robot places the selected cassette onto a cassette player.
The analog portion of said record is then displaced on analog monitor from cassette player.
MIXED MEDIA MEMORY PACK (FIG.
1A) FIG.
1A is the perspective view of a mixed media memory pack.
The first media is high capacity low cost media such as tapes or disks.
The second media is high access speed media such as random access memory
