ABSTRACT:
A rate adaptive magnetic card writer records data on a card having a magnetizable surface while the card is moved by hand through a slot on the card writer. The rate of movement of the card is determined and then used in adjusting the writing of the data such that it occurs at a rate generally consistent with the speed of the card. The written data is thereby reasonably dispersed on the card and can be read by a variable speed card reader.
