Abstract

PURPOSE:To make an index information usable for a long life, by forming the part of noncontacting with a magnetic tape on the circumference corresponding to the index recording track of the roller in contact with the recording plane of a magnetic tape. CONSTITUTION:A capstan toller 4 and a pinch roller 5 consist of upper rollers 41, and lower rollers 42, 52, and the two stage roller is formed in which a prescribed space is provided between rollers 41, 51 and 44, 52, i.e., the parts 40, 50 noncontacting with the tape 3. Thus, at the running of the tape 3, the index recording track 71 on the tape 3 does not contact with the rollers 4, 5. Further, the width of the noncontacting parts 40, 50 can be set slightly greater than the width of the index recording track 71.
