Abstract

A rotary recording medium reproducing apparatus comprises a reproducing stylus for reproducing recorded signals from a rotary recording medium which is recorded with an information signal on a spiral track, by tracing over the spiral track on the rotary recording medium, a reproducing mode setting circuit for setting a reproducing mode of the reproducing apparatus to a special reproduction mode such as a quick-motion reproduction mode in which the reproducing stylus successively shifts to and traces over adjacent track turns of the spiral track and a still picture reproduction mode in which the reproducing stylus repeatedly traces over the same track turn of the spiral track, besides a normal reproduction mode in which the reproducing stylus successively and continuously traces over the spiral track, a stylus pressure control signal generating circuit for generating a stylus pressure control signal of a voltage having a magnitude in accordance with the set reproducing mode, according to the reproducing mode set by the reproducing mode setting circuit, and a stylus pressure applying circuit applied with the stylus pressure control signal generated by the stylus pressure control signal generating circuit, for applying a stylus pressure to the reproducing stylus.
