Abstract

Variations in velocity in high density recording on a magnetic card seriously increase the error rate. A device for eliminating velocity variations in a system in which a magnetic card is biased against a fixed rail by means of springs is shown.

Continuous Spring Rail

Variations in velocity in high density recording on a magnetic card seriously increase the error rate. A device for eliminating velocity variations in a system in which a magnetic card is biased against a fixed rail by means of springs is shown.

A number of support springs are attached to a spring support rail. An anchor spring is attached to a long continuous spring rail. The rail is of spring material and is flexible. It is attached only to the anchor spring and, as shown, provides a force at all times, on the edge of the card as it is being fed. Thus, the variations in velocity which would be caused by a card moving from spring to spring are eliminated.
