MAGNETICS PERFORMANCE CHARACTRISTICS
Media speed: The circuit decodes data reliably at 3 to 50 inches per second (ips).
Card Jitter: The circuit decodes data with bit cell spacing errors up to 15% (30% for subintervals)
at media speeds of 3 to 50 ips.
Low Amplitude Reading: Media with data recording amplitudes below ANSI and ISO
specifi cations can be read. Media amplitudes of 30% (210 bpi) and higher, or 40% (75 bpi) and
higher, can be read at speeds of 10 ips or greater.
Media Specifi cation: Media with magnetic coercivity of 300 through 4000 Oersted can be reliably
read.
