Characteristics of Miniaturized Air-Bearing Flying over Discrete Track Medium

We have developed a simulation method in which grooves are virtually distributed on a slider air-bearing surface instead of on a grooved medium surface and used it to investigate slider flying performance. The characteristics of miniaturized air-bearing flying over a discrete track medium (DTM) with...
