Abstract: PURPOSE:To ensure the stable tape driving by giving a pattern display to a leader tape at the tip of a tape for discrimination of the contents and the type of the cartridge tape and applying the feedback to a reel motor after recognizing the pattern display through a magnetic tape device. CONSTITUTION:A transparent leader tape part A at the tip of a cartridge tape 10 has a fixed length, and the information is recorded to an opaque recording tape part B. The tape length is patterned and displayed at the part A. For instance, two opaque display parts C are used with a tape of 400 feet, and an opaque display part C<1> is used with a tape of 800 feet. Thus the length of the cartridge tape is discriminated. Then these patterns C and C<1> are read by a tape tip detecting photodetector 9 and a light emitting element 11 and then fed back to the reel motors which drive the reels 1 and 2. Thus it is possible to calculate the tape reel winding quantity form a calculating expression corresponding to the cassette tape length.
