1,167,625. Bearings. INTERNATIONAL BUSINESS MACHINES CORP. 21 Sept., 1967 [23 Jan., 1967], No. 43026/67. Heading F2A. A fluid bearing comprises a rigid member 12 with a flat or convex surface 10 containing a groove 24 the extremities of which diverge towards the trailing end of the member. In Figs. 1 and 3 a plurality of V-shaped grooves 24 are at the leading end of member 12, the central portion of the leading groove opening into end surface 20. A tape 14 is drawn between supports 26, 28 and air drawn along with the tape forms a film between tape 14 and member 12. Due to their shape the grooves draw air away from under the tape so that the tape drops towards member 12. Beyond the grooves, the tape is spaced from the member 12 by a uniform gap h which extends up to a portion at the trailing end of the block. In Fig. 4 (not shown), grooves (24) are curved. In Fig. 6 (not shown), grooves are provided at each end of the member to allow tape reversal. The member may contain read and write heads. The tape may be replaced by a flexible disc.
