ABSTRACT:
A method of assisting a user to supply tape cassettes from a tape library to an on-line storage facility that has a limited capacity A and facilitates automatic feeding of the tapes to VTRs in a series of events comprises the steps of preparing a master list setting forth the events in a sequence from top to bottom and tape cassettes respectively corresponding thereto, identifying tape cassettes currently in the on-line storage facility, and selecting a critical load area consisting of a predetermined number of events N from the current top of the list, where 0.ltoreq.N.ltoreq.A. A determination is made of a first set consisting of first priority tape cassettes to be housed in the on-line facility for subsequent automatic feeding to the VTRs, a second set consisting of second priority tape cassettes to be withdrawn from the on-line storage facility to make room for insertion of additional tape cassettes from the tape library and retained for subsequent reinsertion in the on-line storage facility, and a third set consisting of zero priority tape cassettes to be withdrawn from the on-line storage facility and returned to the tape library. The results of this determination are signaled to the user of the system.
