Optical disk controller which sets sampling interval according to rotational speed of optical disk
First Claim
Patent Images
1. An optical disk controller for performing signal processing for an optical disk, comprising:
- an error correcting section for performing error correction for data read from the optical disk and outputting an error correction result;
a status generator for generating status reports based on the error correction result outputted by the error correcting section, each representing the operation state of the optical disk controller; and
a status sampling section for selectively sampling the status reports, said status sampling section comprises a sampling interval setting portion for setting a status sampling interval, wherein the sampling interval setting portion sets the sampling interval according to the rotational speed of the optical disk.

Abstract
The optical disk controller of this invention that reduces the frequency of output of status reports to relieve the burden of a system controller includes: a status generator for generating status reports each representing the operation state of the optical disk controller every sector of a disk; and a status sampling section for sampling the status reports at a set sampling interval. When a generated status report matches with “sampling abort” status stored in a sampling category storing portion, status sampling is aborted.
