MAGNETIC DISCRETE TRACK RECORDING DISK

摘要

PROBLEM TO BE SOLVED: To provide a method for manufacturing a magnetic recording disk which provides the most suitable signal-to-noise ratio( SNR ) and resolution and the best performance. SOLUTION: In a method of forming discrete track recording patterns on the magnetic recording disk, the discrete track recording patterns can be formed on consecutive NiP layers 130 through the discrete track recording patterns in one embodiment. The discrete track recording patterns can be otherwise formed on a substrate 120. COPYRIGHT: (C)2004,JPO
