    Abstract: A plurality of tape guides are moved to wind a magnetic tape on a rotatable cylinder when the magnetic tape is to be loaded. An auxiliary guide mounted on a chassis of a magnetic recording and/or reproducing apparatus in position is made to touch the magnetic tape during a period for which the magnetic tape is being loaded, but it does not touch the magnetic tape when the magnetic tape has been loaded. The auxiliary guide can be protruded toward the magnetic tape from between the tape guides moving to touch the magnetic tape during the period for which the magnetic tape is being loaded so that the magnetic tape can be kept to a predetermined span.
