DEVICE AND METHOD FOR RECORDING DATA AND DEVICE AND METHOD FOR REPRODUCING DATA

摘要

PROBLEM TO BE SOLVED: To efficiently suppress the occurrence of data errors while ensuring real time performance in the case of recording or reproducing data such as compressed image data where the real time performance is essential. SOLUTION: In this data recorder, a temporary storage register 34 temporarily stores information denoting the importance of a cluster being the recorded unit of data in the case of recording the data being the components of an AV data stream on a magnetic disk 5. On the occurrence of a write error, the importance of a cluster having the write error is recognized by referencing the temporary storage register 34 and the degree of retrial of writing the cluster having the write error on the magnetic disk again is selected depending on the importance of the cluster.
