Abstract
In a method and apparatus for scanning tape including a recording medium with a scanning head, the head runs along the circumference of a circle having a central axis inclined by a predetermined angle with respect to a reference direction. The tape is guided along the elliptical circumferential surface of an elliptical cylinder with the longitudinal direction of the tape substantially perpendicular to the reference direction and the width direction of the tape substantially parallel to the reference direction, the elliptical cylinder being formed by a generatrix which includes a point on the circumference of the circle and is substantially parallel to the reference direction, while the point moves along the circumference of the circle. The tape is scanned with the scanning head while the scanning head runs along a portion of the circumference of the circle, the portion of the circumference of the circle being associated with a sector of the circle which sector has a radius substantially perpendicular to the reference direction and extends to both sides of the radius each by a substantially equal angle about the central axis.
