摘要
New metal particle (MP) media was developed for use with giant magnetoresistive (GMR) heads. We confirmed the capability of constructing a helical scan magnetic recording system exceeding 3 Gb/in(2) recording density, because of sufficient signal-to-noise ratio (SNR) under test conditions at 6.74 Gb/in(2) of read-track-base calculations with the media (magnetic layer thickness = 50 nm, magnetic particle size = 45 nm, and surface roughness Ra = 1.8 nm). Low media partial-abrasive properties are incorporated to avoid excessive head gap material wear.
