摘要： A system and method for forming servo patterns on magnetic media is disclosed. A magnetic film coated with a layer of polystyrene is stamped with a nickel stamper reproducing the negative image of the stamped pattern on the polystyrene. Ions are then accelerated towards the surface of the polystyrene, which stopps the ions in the areas where the polystyrene is thick and allows the ions to penetrate through to the magnetic layer in the areas where the polystyrene is thin. The ions, which penetrate through to the magnetic layer, interact with the magnetic layer altering the magnetic layer's structure reducing its coercivity (Hc) and remnant moment (Mrt). This reproduces the stamped polystyrene pattern on the magnetic layer. The polystyrene is then removed by oxygen plasma etching the surface leaving behind a patterned magnetic media.

摘要： A system and method of calibrating optical measuring equipment includes optically measuring discrete objects of a first known predictable pattern from a calibration apparatus, wherein the first known predictable pattern is a bit pattern. A recording surface optical reader is calibrated based on the optically measuring. Using the first known predictable pattern, contamination is filtered from the results of the optically measuring.
