  • Patent number: 6018442
    Abstract: An apparatus having a read/write head for reading and/or writing information on an information carrier which may be in the form of a tape or disc. The head is mounted on a drum which is supported on a shaft which axially rotates the drum so as to move the head relative to the information carrier, which in the case of a tape winds around the drum. The drum is supported in the axial direction by a thrust bearing and in the radial direction by fluid bearings (25) and (26). The thrust bearing has adjoining surfaces of which at least one is made of cemented tungsten carbine, the other possibly being of steel. Thus, there is low friction and low wear. During operation of the apparatus the bearing surfaces remain in contact, thereby forming an electrical coupling to a grounding frame of the apparatus so as to limit static charging of the rotating drum.
