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.
Claims3
In a hand-held transducing device for transducing information signals relative to a stationary record carried on a sheet of material having at least one pair of mutually perpendicular side edges, a housing small enough to be readily held in one hand, a movable transducer carried by said device for tracing a predetermined information path on the record, and means for holding a record in stationary transducing relation to said transducer, the last named means including a panel, means supporting said panel in predetermined spaced relation with respect to said transducer, passage means for admitting the sheet into the spacing defined between said panel and said transducer, and means carried by said panel for engaging said pair of side edges of the sheet to register the predetermined information path of the record with respect to said transducer, said passage means including slots respectively defined along substantially mutually perpendicularly adjacent sides of said panel, that part of said panel disposed between said adjacent slots being free to permit one of said slots to continue into the other upon lifting of said part of said panel.
In a hand-held transducing device for transducing information signals relative to a stationary record medium carried on a sheet of material, a housing small enough to be readily held in one hand, a transducing assembly within the housing including a rotatable body, a transducer element carried by said body during rotation thereof to trace a predetermined record path, and means carried by said housing for registering the sheet with respect to said path comprising a holder assembly for receiving a sheet therein, means coupling said holder assembly to said device, said holder assembly including a panel of semi-rigid material to be disposed in substantially overlying relation to said record path, first and second elongate slots formed along first and second adjacent side edges of said holder respectively for receiving a sheet therethrough to be disposed in transducing relation with respect to said transducer, and means forming elongate mutually perpendicular abutments opposite said first and second slots respectfully for engaging first and second mutually perpendicular edges of the sheet to register a trace thereon respectively with respect to said predetermined record path of said transducer.
