摘要
A write circuit includes a waveform correction circuit for changing a waveform of leading and trailing portions of a write current so that a read circuit of the magnetic recording apparatus for magnetically recording at a recording density lower than the predetermined recording density can read the recorded signal. The waveform correction circuit is inserted between a coil of a magnetic head of the magnetic recording apparatus and a binary signal generator circuit when it receives a selection signal for selecting a recording state corresponding to the magnetic recording apparatus with the low recording density.
