ABSTRACT:
Method and apparatus for advancing tape having an information recording surface relative to an information transducing head provide a sliding surface at a distance from the head, preferably paralleling a tape advance path in a transducing mode in which the tape moves with its information recording surface in engagement with the transducing head. For a fast tape advance mode, such as rapid rewind or fast forward, the tape is moved to the sliding surface away from the head. Preferably, the tape is so moved with the aid of a pressure gradient generated on a surface of the tape opposite its recording surface. The tape is then advanced along the sliding surface in the fast tape advance mode in spaced relationship to the transducing head, while preferably being maintained with the pressure gradient on the sliding surface for the duration of the particular fast tape advance.
