A disk recording apparatus (10) is designed for recording predetermined input data DIN onto a disk-like recording medium (21) having recording tracks on which predetermined absolute address information has been recorded in advance. The disk recording apparatus comprises input memory control means (15), (16) and (17) which successively store the input data DIN for every predetermined recording units (FB0), (FB1), (FB2), ----, (FBN) and read the data from given positions (t0), (t1), (t2), ----, (tN) for each of said predetermined recording units to send them to recording means (20) and (22). The apparatus further comprises abnormal condition detection and control means (15) which always monitors the absolute address information on said recording tracks to detect any abnormal condition based on said absolute address information. When abnormal condition has developed, the control means (15) calculates the return time required for said recording means (20) and (22) to return to the head position of said recording unit that is being recorded on the recording track, and controls and records the reading positions (t0), (t1), (t2), ----, (tN) of said input memory control means (15), (16) and (17) in advance by the number of recording units that correspond to the calculated result. Probability of elimination of the recorded data is thus avoided even when abnormal condition has developed in the recording means (20), (22) while the input data DIN are being recorded. |
