Title:
磁気記録装置および磁気記録用集積回路
Document Type and Number:
Japanese Patent JP4095749
Kind Code:
B2
Abstract:
A magnetic recording apparatus equipped with a recording circuit for generating a recording current corresponding to an input recording signal, a magnetic head, operable in response to the generated recording current, for recording, in a magnetic recording medium, data corresponding to the input recording signal, and a waveform shaping section for shaping the generated recording current such that a current value of said recording current approximates to a predetermined value while keeping thereover throughout a period corresponding to the data length. Both the recording circuit and the waveform shaping section may be mounted in an integrated form on a single microchip. The result is that the input recording signal can be transferred at high speed as measures are provided to reduce both a rise time and a fall time of the recording current.
