摘要： A method for detecting leakage from a disk drive enclosure includes providing a lubricating composition having a lubricating material and a tag material therein. The tag material has a volatility characteristic that is amenable to analysis. The method includes measuring a concentration of the tag material in the vapor phase. By measuring a concentration of the tag material, a leak rate of the lubricating material can be determined. The lubricating composition may include a perfluoropolyether lubricating material and a halogenated sulfur tag material such as SF6 and/or S2F10.

摘要： The present invention is a magnetic disk drive for reading or writing magnetically, comprising: (i) a base plate; (ii) one or more of magnetic disks; (iii) a hub fixedly attached to the disks for supporting the disks; (iv) a motor operable to rotate the hub; (v) one or more of magnetic read/write heads, each associated with the surface of a disk; (vi) an actuator for supporting the heads and moving the heads across the disks; (vii) a support shaft attached to the base plate; and (viii) a load/unload structure for displacing the heads from the disk comprising an elongated body, a base portion fixedly attached to the base plate and a plurality of ramps extending outwardly from the body. The body of the structure is mounted through one or more holes in the body onto the support shaft so that the support shaft extends along the length of the body to support the structure.

摘要： The invention relates to an improved high performance magnetic recording device. The recording device comprises a magnetic recording disk, a slider having a transducer for reading or writing data on the disk, a motor operable to rotate the disk at speeds greater than 7000 RPM and an actuator connected to the slider to move the slider across the disk. The trailing surface of the slider is coated with a low surface energy film to prevent build up of droplets of liquid contaminants.
