ABSTRACT:
A hand-held transducing device for magnetically recording upon and playing from stationary records of a type adapted to be carried on back of a photograph or the like employs a rotating head for transducing information with respect to the record and means apart from the record for guiding the transducer to travel in a record trace while progressively varying the pitch of the head with respect to the track so as to vary the track density across the surface of the record, thereby extending the playing time of a record.
