Method and arrangement for magnetic digital recording with high frequency biasing |
摘要 |
The invention relates to a method and circuit arrangement for magnetic recording of a digital data signal composed of a set of transitions. A recording signal is formed by superposition on the data signal of a high frequency, constant amplitude, magnetic biasing signal Sp. The biasing signal is phase-modulated relative to the data signal transitions. The invention remedies "peak shift" and can be applied to any rectangular or sinusoidal biasing signal.
