ABSTRACT:
A disc player in which a servo-driven carriage supporting a pickup arm assembly via a block mounted thereon is movable along a linear path substantially normal to an imaginary radial line of a disc turntable, the level of the block being adjustable as required relative to the carriage. A gimbal support mechanism, a pickup arm lifting mechanism, a pickup arm offset angle detecting mechanism and a pickup arm positioning mechanism are all encased within the block, thereby assuring a compact construction, successful slashing of noisy vibrations of mechanical parts conventionally causing lowering of reproduction quality and simple adjustment after replacement of mechanical parts.
