Claims

[Scope of Claim for Utility Model Registration] The lead-in area contains data on the required playback time from the start position of the program area to the lead-out start position, and the program area contains the data to be played and the required playback time from the start position of the program area. Name address data as time data is recorded at predetermined intervals, and data indicating lead-out in the lead-out area and address data as data of the required playback time from the start position of the program area are recorded at predetermined intervals. In a disc record reproducing apparatus, the disc record reproducing apparatus has a reproducing means for reproducing a disc record using a pickup, and a search means for searching for desired data to be reproduced in the program area by key operation. Move the disk record in the radial direction at high speed. a pickup moving means; a pickup kicking means for moving the pickup thinly in a radial direction of the disc record by a set amount by driving an actuator in the pickup; and a lead-out start address from which the pickup is read out from the lead-in area. a detection means for detecting that the lead-out start address is located in a limited area between the limit start addresses set inward from the lead-out start address; A disc record playback device comprising: a means for inhibiting movement in the outer circumferential direction for inhibiting feeding in the direction.
