ABSTRACT:
A double-sided reproducing disk player wherein reduction in size and simplification in structure of a carriage can be attained and reduction in number of parts and simplification in construction of the entire arrangement can be attained to attain reduction in overall size and also in production cost. The player comprises upper and lower face guide mechanisms for guiding a carriage, on which an optical pickup is carried, along upper and lower surfaces of a disk, respectively. The upper and lower face guide mechanisms are carried on a carrying device which is supported for tilting motion on a stationary frame of the player, and the tilt angle of the carrying device with respect to the stationary frame is adjusted by a tilt angle adjusting device. The tilt angle adjusting device includes an eccentric member on the stationary frame and a spring for biasing the carrying device into cooperation with the eccentric member. The eccentric member is rotated by a motor in response to a tilt angle of the carrying device detected by a tile angle detecting sensor.
