Means are provided which are adapted to guide a portion of an information carrier consisting of a strip in the form of a loop. A sensing device is movable along a predetermined path into and out of engagement with said portion of said strip. Mode control means are operable to set the apparatus for any of a plurality of modes of operation. One of said modes is a fast rewind mode. Locking means are movable between an inoperative position, in which they are clear of said path, and an operative position, in which they extend into said path and are adapted to hold said sensing device clear of said strip. Means are arranged to more said locking means to and hold them in said operative position in response to the setting of the apparatus for said fast rewind mode and to move said locking means to and hold them in said inoperative position in response to the setting of the apparatus for another of said modes.
