An apparatus for reproducing information from a recordable optical disc having an information recording area for recording a plurality of information pieces and an index information recording area for recording index information with respect to the plurality of information pieces. The apparatus includes a driving device for rotationally driving the optical disc, a pickup device for irradiating a light beam onto the optical disc so as to read information recorded on the optical disc, a transferring device for transferring the pickup device in a radial direction of the optical disc, a memory for storing a temporary index information, and a control device for controlling the driving device, the pickup device and the transferring device and for producing the temporary index information on the basis of a read information read by the pickup device. The control device produces and stores the temporary index information into the memory when no index information is recorded on the index information recording area. Accordingly, desired information can be reproduced from the program area of a partial disc.
