Abstract
We have investigated magnetic recording on multilayer perpendicular media using a conventional peak detect channel and a commercial magnetoresistive recording head. A linitc impulse response filter was used to equalize the impulse response from perpendicular media into a unipolar pulse. Equalized pulses had a PW50 of 174 nm and a D50 of 131 kfci. Without write precompensation, a linear density of 204 kbits per inch (kbpi) with a 3.3 ns error window margin and a data transfer rate of 75 Mbits/s was measured with an error rate of 4 × 10-7. The signal waveform was stable and had good up-down amplitude symmetry.
