Abstract
A magnetic-tape cassette apparatus includes a magnetic head unit having a magnetic head with a head face and head gap defining a head gap plane. To each side of the head face, in the direction of tape transport, a tape guide is provided adjacent the head face and having a radius of curvature smaller than that of the head face. At one end of each tape guide a height limiter is arranged, having a limit surface facing the tape such that a line connecting the limit surfaces is perfectly perpendicular to the head gap plane. The apparatus includes a control member or surface for keeping a lateral edge of the tape constantly in contact with the limit surfaces during tape transport.
