Abstract
Abstract Disclosed is a novel information card having a conductive control stripe in addition to a known magnetic stripe and a machine for accepting the novel card and prior art cards and for transporting the cards at different pre-set rates depending on the rate at which the card was transported when recorded. The control stripe on a card actuates a control circuit of the transport machine by closing a selecting circuit through a card sensor so that the machine will transport cards with and without stripes at a selected of the pre-set rates.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
169 words
A record and machine control card member for use in an audio transducing machine having a card guide path, a transducer oriented along said guide path, a drive operable at a selected of a plurality of pre-set drive speeds for causing transducing of information from said card member at one of said selected speeds and being responsive to said machine control on said card member for transducing of information on said card member at another of said selected speeds, the record and machine control card member comprising: a generally planar card having at least two discrete support surface areas; an elongate magnetic media carried on one of said support surface areas being transducable by said transducer at a selected one of said pre-set speeds upon energization of said drive; and an electrically-conductive drive speed control media carried on another of said discrete support surface areas in co-extensive relationship with said magnetic media to actuate said drive to another selected speed incident to energization of said drive by said card.
Claim 2
Dependent Claim
169 words
A record and machine control card member for use in an audio transducing machine having a card guide path, a transducer oriented along said guide path, a drive operable at a selected of a plurality of pre-set drive speeds for causing transducing of information from said card member at one of said selected speeds and being responsive to said machine control on said card member for transducing of information on said card member at another of said selected speeds, the record and machine control card member comprising: a generally planar card having at least two discrete support surface areas; an elongate magnetic media carried on one of said support surface areas being transducable by said transducer at a selected one of said pre-set speeds upon energization of said drive; and an electrically-conductive drive speed control media carried on another of said discrete support surface areas in co-extensive relationship with said magnetic media to actuate said drive to another selected speed incident to energization of said drive by said card.
Claim 3
Dependent Claim
108 words
A record card member for use in an audio transducing machine having a card guide path, a transducer oriented along said guide path and a drive operable for effecting transducing of information from said record card member, said record card member comprising: a generally planar card having two discrete support surface portions; an elongate magnetic media fixed to one of said support surface portions of said card to provide an information signal transducable by said machine; and an electrically-conductive media fixed to the other of support surface portions in parallel, co-extensive relationship with said magnetic media to provide a signal adapted to be sensed for drive speed control.
Claim 4
Dependent Claim
108 words
A record card member for use in an audio transducing machine having a card guide path, a transducer oriented along said guide path and a drive operable for effecting transducing of information from said record card member, said record card member comprising: a generally planar card having two discrete support surface portions; an elongate magnetic media fixed to one of said support surface portions of said card to provide an information signal transducable by said machine; and an electrically-conductive media fixed to the other of support surface portions in parallel, co-extensive relationship with said magnetic media to provide a signal adapted to be sensed for drive speed control.
Claim 5
Dependent Claim
33 words
A record card member as in claim 2, wherein said magnetic media is carried on one face of said card and said electrically-conductive media is disposed on the same face of said card.
Claim 6
Dependent Claim
33 words
A record card member as in claim 2, wherein said magnetic media is carried on one face of said card and said electrically-conductive media is disposed on the opposite face of said card.
