Abstract

PURPOSE: To change a screen prior to a branching operation over to a screen after the branching operation at a high speed by providing several audio tape units and by recording block information on a branch destination on an audio tape differing from that with block information prior to the branching operation.
CONSTITUTION: Audio tape units TR1 and TR2, connected to a bus by way of interfaces I/F1 and I/F2, are used by switching. When access to block M on a tape of unit TR1 is attained, unit TR2 drives the tape by a control program stored in ROM so that a block indicated by index code A1 of block M, e.g. K will be at a read position. Video information of block M is read to TV by an application program sotred in RAM, but when a branch is made, a read from unit TR1 stops and block K of unit TR2 is read out. At the same time, unit TR1 is so driven by an index code of block K that a branch-destination block of the tape of unit TR1 will be at the read position.
