摘要： A magnetic tape which is run at a speed of 4 m/sec. or higher and has recording tracks with a width of 21 μm or less, and which includes a non-magnetic support, at least one magnetic layer formed on one surface of the non-magnetic support, and a backcoat layer formed on the other surface of the non-magnetic support, wherein servo signals for controlling tracking are recorded on the magnetic layer or the backcoat layer, the value of (α/W) X (V/f) is 10 [s−1] or less, and/or the value of (α/W) is 0.1 or less, wherein V [mm/sec.] is the tape-running speed; α [μm] is an amount of a weave with a cycle of f [mm] on one edge of the tape or the other edge thereof, as the reference side, for the running of the tape; and W [μm] is a width of the recording track. The magnetic tape can decrease PES and off-track and thus is excellent in servo tracking performance.

摘要： A single reel tape cartridge capable of achieving high-speed read/write access to tapes at high density by enhancing the molding accuracy of lower flange and eliminating inclination and waviness of flange walls is provided. A reel incorporated in a main case is composed of an upper flange, a lower flange, and a boss which is integrally plastic-molded with the lower flange for taking up a magnetic tape. An exit port for allowing an operating nail of an unlock tool to get in and out is open on the bottom wall of the boss. The lower flange is molded in the state that a bridging piece extending along radial direction of the lower flange is formed in the exit port, so that resin flow to the flange wall radially outside the exit port is promoted. The bridging piece is removed after the lower flange is molded.
