Magnetic recording measurements of sputtered media on tape at an areal density of 14 Gb/in
Abstract
Magnetic recording characteristics of a thin-film sputtered media on tape are studied with an HDD head in a high precision nano- positioning system. Signal spectrum roll-off slope is used to determine the effective magnetic spacing to be about 108 nm. The optimum broadband SNR at a linear density of 254 kbpi is 10 dB with a GMR read width of 0.1 μm. The estimated minimum track pitch, limited by side-track interference, is approximately 0.45 μm. © 2009 IEEE.
