Read/write machine for magnetic stripped document card |
| abstract |
A read/write machine for a document card having a strip of magnetic material thereon, the machine including a magnetic read/write head and a pair of nipped rolls between which the card moves for transporting the card and particularly its stripe of magnetic material over the read/write head. Controls are included for selectively returning the card to its original position in the machine after a reading or writing operation has occurred for allowing the operator to remove the card from the machine, or alternately automatically moving the card in a second pass over the head in the same direction as the first pass of the card thereover so that any data written on the card during its first passage over the head may be read therefrom by the head, or alternatively causing the card to move in three forward passes through the machine, with the third pass being used for checking the magnetic bits as previously recorded and previously read during previous forward passes of the card through the machine. |
