Abstract

1,045,020. Recording and play - back. BRITISH OXYGEN CO. Ltd. April 2, 1965 [April 10, 1964], No. 14976/64. Heading G5R. In apparatus for playing conventional disc records, the pick-up arm 3 is supported on a cross-piece 5 which can move rectilinearly on bearings 10, 11. The surfaces of these bearings are arranged to have pressurized gas, such as carbon dioxide, supplied thereto, thus enabling the pick-up head to move in a substantially frictionless rectilinear manner.
