Title:
METHOD FOR REDUCING ERROR CAUSED BY IMPACT
Document Type and Number:
Japanese Patent JPH10320793
Kind Code:
A
Abstract:

To provide a method to reduce the error caused by impact at a comparatively lower cost.

The error is compensated (108, 111) in accordance with correction data (FF(n-1)) stored in a memory by detecting (100, 102) the impact and responding this detection. This method is applicable to an optical disk player, e.g. an information reading device such as a CD or DVD. The updating of the correction data stored in the memory based on the error which is measured on the detection (104) of the decreasing error by the above-mentioned method, is profitable, and by such a learning programing, the compensation becomes more and more effective at each sequential impact in a certain series of impacts.
