Title:
METHOD AND DEVICE FOR READING MAGNETIC STRIPE
Document Type and Number:
Japanese Patent JP3530583
Kind Code:
B2
Abstract:
PURPOSE: To accurately read a magnetic stripe of a two track system.
CONSTITUTION: A track of a bit of zero is reproduced with a head 11, and the track information of one-bit is calculated with a CPU 10 by using only an output pulse obtained through an amplifier 12 and a waveform shaping circuit 13 is obtained, and bit arrangement is reproduced. Thus, the insertion defect of the magnetic stripe at the reading and an error due to inclination of a scan are reduced, thus read accuracy is improved.
