The read/write performance of a thin-film single-pole head and a double-layer perpendicular disk was evaluated, including error rate testing. An AMR head with a track width of 1.4 μm was used as a reading head. The channel of the tester was a PR4ML with 8/9 endec. For the testing, readback waveform of the MR head was transformed into a suitable pulse shape with a differentiator for the testing. A D50 of 185 kFRPI and a PW50 of 130 nm were obtained with this equalization. A byte error rate of 10-6 was obtained at 310 kFRPI.
