摘要： Method (220) and apparatus (300) for writing servo position data (184) to a data storage medium (180). The medium is adapted for use in a data storage device (100) wherein the medium is operably moved in ambient air at a nominal speed to establish a nominal fly height of a data transfer member (118) with respect to the medium. The medium is placed (222) into an enclosure (256) housing a gaseous environment having a density less than that of ambient air. The medium is moved (224) by a motor (254) at a write speed substantially greater than the nominal speed to cause a writting member (118) to a fly at substantially the nominal fly height, during which the writing member writes (226) the servo position data to the medium. The medium is subsequently removed from the enclosure and installed into the data storage device.

摘要： A method of detecting that a concentration of a low-density gas such as helium in a disc drive is in danger of reaching an unacceptable level includes monitoring a signal varying in response to variations in the concentration of the gas in the disc drive. A criterion is determined based on the signal where the criterion indicates that the gas level is about to reach the unacceptable level. Finally, a flag is set once the criterion is met. A disc drive containing a low-density gas such as helium includes a sensor within the drive that produces a signal responsive to variations in the concentration of the low-density gas in the disc drive. The disc drive also includes a processor that monitors the signal and sets a flag if a predetermined criterion is met.
