Abstract
A guide rail system (2) comprising a guide rail member (8) fixed to a base member (1) and a movable rail member (7) engaged with the fixed guide rail member to freely move together with a magnetic head (4) is used by the present invention as a device for guiding the magnetic head in the width direction of a magnetic tape. Linear guide grooves (9a-9d) are formed on those sides of the fixed and movable guide rail members (8, 7), respectively, which are separated from and opposed to each other. Plural rolling members (10) are sandwiched in rolling contact between the guide grooves (9a, 9c) and between the guide grooves (9b, 9d).
