Abstract:
A magnetic tape recording medium comprising:a data area on which data tracks having an azimuth angle &thgr;Â° are recorded and reproduced sequentially; and two servo tracks disposed between both end portions of said magnetic tape recording medium in a width direction of said magnetic tape recording medium, each of said two servo tracks extending in a longitudinal direction of said magnetic tape recording medium and having therein a previously recorded servo track signal that includes position information recorded in the longitudinal direction representing a position of said magnetic tape recording medium and also includes tracking information recorded in parallel to said data tracks, wherein said azimuth angle &thgr;Â° satisfies an equation of: 0&leq;Î¸&leq;tan-1&af;(10&it;paÃ—L),where a width of said magnetic tape recording medium in the width direction is expressed as L(m), a data track pitch in said data area is expressed as p(m), and the greatest dimension change rate of said magnetic tape recording medium in the longitudinal direction due to a temperature and humidity is expressed as (a) (%) 10 p.
