Abstract

An apparatus and method are provided for transducing information with respect to record cards such as oblong cards containing magnetic recording material. In one form, a magnetic record card is made to conform or extend parallel to the cylindrical surface of a drum supporting a magnetic transducer which rotates to scan one or more selected tracks of the card. The card may extend in a circular or helical path while scanning occurs or may be driven in such a path during scanning.

4. Magnetic transducing apparatus in accordance with claim 1 wherein said first means is operable for deforming a card received thereby into a cylindrical configuration of constant diameter defined by a central axis and said fourth means is operable for causing relative movement between said transducing means and said deformed record card in a direction parallel to said central axis.

5. Magnetic transducing apparatus in accordance with claim 4 wherein said fourth means includes means for effecting relative rotational movement between said magnetic transducing means and a card received by said first means.

6. Magnetic transducing apparatus in accordance with claim 5 wherein said fourth means includes means for rotating said magnetic transducing means to cause it to engage and scan the recording tracks of the arcuately deformed card.

7. Magnetic transducing apparatus in accordance with claim 1 wherein said sixth means includes means for detecting the locations of said parallel record tracks of said card as said relative movement is effected between said card and said magnetic reproduction head in said first and second directions.

8. Card transducing apparatus comprising in combination:

first means for receiving and guiding a record card containing video picture signals recorded on a plurality of parallel tracks which tracks extend oblique to the longitudinal axis of a card received by said first means, said first means being operable to deform the received card to cause its recording surface to become arcuately shaped,

second means for driving a record card along said first means,

third means for stopping the movement of the card driven along and guided by said first means when the card is predeterminately disposed thereon,

fourth means including a magnetic reproduction transducer disposed for scanning a card guided by said first means for reproducing recorded video picture signals from a selected one of said oblique tracks of a card which is predeterminately positioned with respect to said first means and means for rotating said magnetic reproduction transducer in a manner to cause it to repeatedly scan the track of a card which is stopped and predeterminately disposed on said first means, and

fifth means including a video monitor having a viewing screen for receiving the signals reproduced by said fourth means and for displaying the information defined by the track scanned as a still image on said monitor viewing screen.

9. Card transducing apparatus in accordance with claim 8 wherein said first means is configured and operable to arcuately deform a card presented thereto to present the parallel tracks of the card along circular pathway configurations and means for rotating said transducing means to cause it to circularly scan the tracks of a card.

10. Card transducing apparatus in accordance with claim 8 wherein said first means includes means for deforming a card into a helical shape wherein at least a portion of each track of the helically shaped portion of a card extends in a circular path.
