Experimental evaluation demonstrates high-density magnetic recording performance using dual-element heads, suggesting viable pathways for high-capacity storage devices.

Key Points

To investigate the read and write performance of a 2 Gb/in² magnetic recording system using a 1-micron dual-element head and a low-noise recording medium.
Tested a 1-micron trackwidth inductive-write/magnetoresistive-read dual-element head on a Co-Cr-Pt/Co-Cr-Pt-Si dual-layered low-noise medium.
Implemented 8/9 block coding, extended class IV partial response signaling, and Viterbi detection in the read/write channel.
Conducted ontrack and offtrack recording measurements at a magnetic spacing of 0.08 μm.
Achieved a linear recording density of 120 kBPI with a bit error rate of 10⁻⁸ during ontrack evaluation at 0.08 μm magnetic spacing.
Demonstrated a track density resolution of 16.9 kTPI corresponding to a viable 1.5 μm track pitch in offtrack testing.
