Reproducing apparatus

A reproducing apparatus for reproducing a multi-session disc composed of a plurality of sessions, each session comprising a lead-in region corresponding to the start position of each program track stored in the multi-session disc and recording index information including the information of reproduction start time measured from the disc innermost peripheral position, program region recording program tracks storing contents to be reproduced, and lead-out region, comprising:

• an optical pickup for reading out the index information of specified session;
• a session judging unit for judging if the lead-in region of the specified session is the lead-in region of the first session of the multi-session disc or not, on the basis of the information of the reproduction time included in the index information being read out by the optical pickup;
• wherein the session judging unit judges that the lead-in region of the specified session is not the lead-in region of the first session when the reproduction start time of the first program track of the specified session is larger than a specified value;
• further comprising an access retry unit for having the optical pickup accessing other session positioned at the inner periphery of the disc when the session judging unit judges that the lead-in region of the specified session is not the lead-in region of the first session;
• wherein the optical pickup further comprises an innermost peripheral position detecting unit for detecting whether the optical pickup is present at the innermost peripheral position of the disc or not, and
• wherein the access retry unit decreases the moving distance gradually from the specified extent when moving the optical pickup repeatedly in the session of the inner periphery of the disc.
