ABSTRACT:
A disc recorder includes a rotating disc and a transducer for coacting with the disc. A guide member has a guide surface extending transversely of the rotating disc and including a groove extending parallel to the disc. A carriage means for mounting the transducer is positioned generally parallel to and movable along the guide surface. A friction reducing pad is mounted on the carriage means and is movable along the guide surface. Friction reducing cylindrical bearing means are also mounted on the carriage means in spaced relation to the pad and are movable in the groove. A locating member having a locating surface is positioned substantially parallel to the guide surface. A loading means is mounted on the carriage means and engages the locating surface to bias the carriage means toward the guide surface such that the bearing pad engages the guide surface and the cylindrical bearing means engage the groove. Means are provided for moving the carriage means along the guide surface, the carriage means being confined to move only in a direction substantially parallel to the plane of the rotating disc.
