ABSTRACT:
A reproducing apparatus of a recording medium, which has address data recorded thereon, a set of data discretely recorded in a plurality of small recording areas thereon, and information indicative of connective relationships between the small recording areas recorded thereon. The reproducing apparatus includes a readout device, a memory, and a controller. The readout device reads data and address data recorded on the recording medium. The memory stores the information indicative of connective relationships between the small recording areas in the data read by the readout device. The controller controls the readout device in high-speed reproduction to repeatedly make an access in accordance with the information stored in the memory and read the data stored in the small recording areas in units of a predetermined data amount. The controller further executes control, when the readout device has moved to a position outside a preceding small recording area after an access, so that the read means will access a subsequent small recording area in a connective relationship with the preceding small recording area. When the address corresponding to the position in the subsequent small recording area, reached after this accessing operation is within a predetermined range of the start address of the subsequent small recording area, then the readout device reads data from the recording medium starting at the position reached.
