Abstract
PURPOSE: To widen the application range of a magnetic tape device by previously recording a specific code signal at the head and tail of a digital block and then by controlling the operation of a sound generating method on the basis of whether the specific signal appears or not.
CONSTITUTION: An input sound signal, after being amplified A, is supplied to head D by way of gate B1 controlled by a signal from central controller E and then recorded on a tape. Then, the control signal from unit E closes gate B1 and opens B2; and a preamble signal with a specific code indicating the head of a digital block from unit E is written and after following digital data, a post-amble signal with a specific code indicating the tail of the block is also written on the tape. As a result, a sound signal and digital signal are written in different regions on the same tape and in reproduction, specific codes are detected by controller E through decoder J to turn OFF relay R of a sound circuit, thereby reproducing data.
