Abstract

Access to a large number of records is enhanced by independent cascade and parallel operation of a plurality of record handling apparatus. Such records may include film, cards, magnetic tape, magnetic disk packs, or any other form of readable or writable records.

Random Access Record Storage

Access to a large number of records is enhanced by independent cascade and parallel operation of a plurality of record handling apparatus. Such records may include film, cards, magnetic tape, magnetic disk packs, or any other form of readable or writable records.

The records are stored in main record storage accessible by X-Y (carriage- elevator) mechanism 10, disposed between open-sided facing storage walls or arrays 11. A plurality of such arrays may be provided. Records or containers having a plurality of records are selectively fetched and stored by carriage 10, with respect to a plurality of storage compartments in each storage wall 11. At one end of the travel path between the storage walls of carriage 10, there is a plurality of record transporters 14. These transporters selectively exchange records with carriage 10 for respective storing and fetching operations. On a fetch operation, the record is transferred from carriage 10 to transporter 14, thence, to buffer record storage 15. Record storage 15 may be constructed in the same manner as the main record storage, but is of a smaller geometry for reducing access times. In addition to receiving records from main storage 11, one or more transporters 14A may exchange similar records from other main storage walls, not shown, to buffer storage 15.

When the record is to be processed, suitable computer-generated commands are supplied to buffer record storage 15 for transferring the buffered record through one of the plural record transporters 16, to a selected one of processing stations 17. Each transporter 16 communicates between buffer record storage 15 and a respective bank of processing stations 17. Such processing stations may be card readers or writers, magnetic tape units, and the like.

The record, upon reaching position 18 of transporter 16, is exchanged or transferred from transporter 16 to a traveling record loader and unloader, contained generally in area 19 and traverses just above processing stations 17 in the respective banks. The...
