Abstract
An information recording disc has a connecting region formed between a parallel program recorded region containing a plurality of parallel information programs and a single program recorded region containing a single information program which is to be reproduced after one of the parallel information programs is reproduced. Each of the parallel program recorded region and the connecting region includes track turns having vertical blanking parts recorded with vertical blanking periods of video signals, and at least one of the vertical blanking parts in each track turn is recorded with an address signal including a first code indicating whether an information program recorded in a track turn of a region is a single information program or a parallel information program, a second code indicating whether the region is the parallel program recorded region or the connecting region, a fourth code indicating the number of information programs recorded in the region, and a fifth code indicating the program number of the program recorded in the region. A reproducing apparatus includes a reproducing element for reproducing information signals from the disc, and the reproducing element is kicked within the vertical blanking part based on the value of the reproduced fourth code during a normal reproduction of a parallel information program.
