Abstract

In order to reduce the wear on magnetic-stripe read and write heads, it is desirable to extend the heads into contact with the magnetic stripe during reading and writing but to retract the heads during return passage in preparation for the next read or write operation. An exemplary application is the read and write heads associated with a passbook printer for reading the magnetic stripe on the passbook in conjunction with printing transaction entries on pages of the passbook. This article shows a simple track in each side frame of the magnetic reader for extending the head into contact and permitting return travel out of contact of the stripe.

Integrated Magnetic Stripe Reader Recorder

In order to reduce the wear on magnetic-stripe read and write heads, it is desirable to extend the heads into contact with the magnetic stripe during reading and writing but to retract the heads during return passage in preparation for the next read or write operation. An exemplary application is the read and write heads associated with a passbook printer for reading the magnetic stripe on the passbook in conjunction with printing transaction entries on pages of the passbook. This article shows a simple track in each side frame of the magnetic reader for extending the head into contact and permitting return travel out of contact of the stripe.

The figure shows side frames 11 having an extend track 13 and a return track 15. Magnetic read head 17 and write head 19 are held in carrier 21 under spring load of springs 23. Carrier 21 is driven from right to left and back by lead screw 25 which also may be the same lead screw which controls the print carrier. When carrier 21 is in the home position 27 at the right end of frame members 11, pin members (not shown) are engaged in the rightmost portion of track 15. As lead screw 25 rotates, carrier 21 is driven toward the left, causing the pin members to come against spring 29 which deflect the previously mentioned pin members, causing heads 19 and 17 to enter track 13, thereby extending the heads for a read or write operation across the magnetic surface of the stripe.
