Abstract
A signal recording/reproducing apparatus for use with a tape cassette comprises a cylinder assembly having an outer peripheral surface. The cylinder assembly has mounted thereon heads for recording and reproducing a signal on and from a magnetic tape in the tape cassette, respectively, and a lead formed on the outer peripheral surface of the cylinder assembly so as to helically extend, to define a running path of the magnetic tape on the outer peripheral surface of the cylinder assembly. A pair guides guide the tape so that the tape is helically wound over a predetermined angular extent along the lead upon the recording/reproducing of the signal. The pair of tape guides are located and oriented in their predetermined positions such that the tape guides impart a force to the tape to press the tape onto the lead during recording and reproduction thereby to permit the tape to move along the lead.
