Patent ID: 8130613

Claim:
An optical disc apparatus that reproduces real-time recorded data on an optical disc, the optical disc apparatus comprising: a spindle motor which rotates the optical disc; an optical head which irradiates the optical disc with a laser beam to read recorded data; a reproduction process circuit which processes a signal from the optical head to generate reproduction data; a defect detection circuit which detects a defect in the reproduction data; a plurality of a data identification flags, the quantity of data identification flags being dependant upon a quantity of sectors of data to be reproduced, and each data identification flag being linked to a sector of data to be reproduced; and a control circuit which references a data identification flag indicative of a type of recorded data, controls a reproduction operation, and transfers the reproduction data to be reproduced to a host device; wherein the control circuit accesses a target reproduction block to count the number of sectors to which the data identification flag representing real-time recorded data is attached, and when the count is not smaller than a threshold value, reproduces all the sectors of the target reproduction block, including the sectors to which the data identification flag representing real-time recorded data is not attached, in a real-time reproduction mode.
