Abstract: A reproducing apparatus is provided which can reproduce information in a predetermined order with a simple operation. The apparatus has a reader for reading out information from a recording medium on which a plurality pieces of information are recorded. An actuator changes a relative position of the reader and the recording medium. A signal generator generates a signal corresponding to a predetermined operation. When the reader is reading out information, an access operation controller switches the operation mode of the apparatus from a play mode to a stop mode. The access operation controller then controls the actuator to change the relative position of the reader and the recording medium so that the subsequent information is set ready to be read out.
