发明名称 TAPE CONTROL METHOD
摘要 <p>PURPOSE:To prevent the detection error, etc. of a data block, etc., by repositioning to the point where a tape mark is detected during a magnetic tape is driven to run at a the high speed, and after detecting the tape mark running at a constant speed to reconfirm the detection of the tape mark. CONSTITUTION:During the high speed driving, the presence of the tape mark is detected by a read amplifier 12. Namely, if a tape mark TM is detected at a point (D), the speed of a magnetic tape 2 is changed to a low speed running (b), and of a magnetic tape 2 is changed to a low speed running (b), and repositioned from RT position through (c)-(d)-(e) and returns to a stop position ST, and the tape is stopped. Next, the MPU4 drives the tape 2 at a constant speed (f)-(g). When a decoder 14 detects the tape mark TM from the output of a read amplifier 12, the decoder 14 sets the tape mark TM signal 1 as '1' and outputs it to an MPU4. Following this '1' signal 1, an inter block gap G is detected. The detection of tape mark TM is finally reconfirmed when '1' of inter block gap G 2 is inputted from a decoder 14.</p>
