MAGNETIC_TAPE_SKEW_MEASUREMENT

Published:2009/7/17 1:58:00 Author:Jessie | From:SeekIC

Magnetic strip recorded on tape is scanned transversely with ring-type play-back head, and periods between output pulses generated at crossover points are measured. C1 acquires positive charge for one direction of skew and negative charge for other. Output of detector of C1, which measures this charge, is fed to difference amplifier having microammeter connected between cathodes to read tracking error.-B. R.
