ABSTRACT:
A magnetic medium processing apparatus includes a magnetism reading head for reading magnetic data recorded in a ticket, a peak value detector for detecting peak values of a signal output from the reading head, and a display for displaying the digital peak values detected by the peak value detector. Monitoring the state of reading by the reading head prevents unstable reading of magnetic data irrespective of whether the reading head is worn out.
