VERTICAL MAGNETIC RECORDING SYSTEM |
摘要 |
A vertically anisotropic medium or a vertical recording system for conducting unoriented recording. The system has a terminal for receiving binary signals that are to be recorded, a ring head for causing magnetic change in the medium, and a recording current generating circuit for generating a recording current that drives the ring head. The recording current is a sequence of fine pulses whose polarities change in response to the direction of change of polarities of the binary signal, and nonzero intervals of a neutral level are inserted between the neighboring fine pulses having opposite polarities relative to each other. The pulses are given a duration TW which satisfies a relationship TW < Bmin where the time Bmin is a minimum interval between changes in polarity in the recording current. |
