专利汇可以提供After-processing method of magnetic tape专利检索,专利查询,专利分析的服务。并且PURPOSE: To increase the lifetime of a magnetic tape medium by performing the read/write processing of information to the tape medium and then driving the medium until the rear end of the tape is detected and rewinding the tape.
CONSTITUTION: A magnetic tape controller MTC controls a magnetic tape device MTU; while an electronic computer CPU performs the desired input of the write information or output of the read information to the MTU via the MTC. A program is read by a processor of the MTC, and the processor decides whether an instruction given from the CPU indicates the writing or reading. The write processing if indicated is carried out by the MTU. Then an end signal is delivered when the write processing is over. Thus a magnetic tape is driven by the prescribed length together with erasion of information by an erasion command at and after the end point of the tape medium. The MTU detects a termination mart EOT at a stop point. Then the MTC performs a rewind action when a device end signal DVE outputted from the MTC is detected. Then a main program is completed after the detection of an initiation mark BOT is confirmed.
