摘要： An optical disk apparatus, which decreases probability of impossibility of correcting an error in reading, is provided, where the error results from deviation of a writing-resuming position in resumption of writing. When an amount of data in a buffer becomes not more than a given amount of data, a buffer-underrun-detecting-circuit judges that the data are in a buffer-underrun-condition. According to the judgement, a writing-interrupting-and-resuming-circuit detects an end position of the last pit for writing, and the position is stored in a time-information-memory, and the optical disk apparatus becomes in a pause condition of writing. When the buffer-underrun-condition is avoided, the optical disk apparatus releases the pause condition of writing, and reads the position of interruption of writing from the time-information-memory, and then synchronizes data written on an optical disk and the data for writing. After that, writing is resumed with a given interval formed between the data written and the data for writing.

摘要： A bi-phase mark reproduction apparatus which reduces an error rate of demodulated data by half and improves demodulation ability of ATIP and an optical disk drive device are provided. The bi-phase mark reproduction apparatus includes a data conversion unit which takes out a synchronous code portion, a data portion and an error detection code portion from a bi-phase mark input signal by means of a data separating signal and demodulates data of the data portion and the error detection code portion. The data conversion unit includes a pattern retrieval unit which detects a predetermined error pattern contained in the data portion and a conversion table which decodes the error pattern in accordance with a replacement rule based on bi-phase mark modulation.
