  • Disk apparatus
    Patent number: 6765753
    Abstract: A moisture absorbing agent is used in a disk apparatus. The difference in the moisture absorption amount in the hygroscopic isothermal line between the moisture absorbing agent at a relative humidity of 80% and the moisture absorbing agent at a relative humidity of 95% is not less than 30% in the moisture absorbing stage and is not less than 20% in the moisture releasing stage relative to the dry weight of the moisture absorbing agent.

  • Magnetic recording/reading apparatus
    Patent number: 6667858
    Abstract: Disclosed is a magnetic recording/reading apparatus comprising a ramp formed of a material having at least 30% of a tensile elongation as defined by ASTM D638. The distance c, which is defined as the length between a ramp and a tab measured at the point a/3 apart from the contact portion, a being the contact width of the ramp and the tab, is 0.0015a, or at least 0.015 &mgr;m where a is 10 to 50 &mgr;m.

  • Magnetic recording media and magnetic recording -reproducing apparatus using the same
    Publication number: 20020037438
    Abstract: Disclosed is a magnetic recording media including a lubricating layer containing a lubricant and at least one antioxidant selected from the group consisting of a phenolic antioxidant and an amine-based antioxidant. The lubricating layer permits maintaining a good lubricity over a long period of time between a magnetic head and the surface of the magnetic recording media when the magnetic head performs the sliding contact with the surface of the magnetic recording media in the recording-reproducing stage.
