Abstract:
There is provided a technique for facilitating file marking by adding attribute information to the file according to read of biometric information. Biometric information is read from a living body moving and attribute information abased on the biometric information is added to the file. According to the biometric information which has been read, the direction of the movement of the living body is judged. When the movement direction coincides with a predetermined direction, the file is searched according to the biometric information.

Abstract:
In an optical disk reproducing device, through a provision of a control circuit, movement of focus point of laser beams is set at positions ahead or back to the focus position causing to enter into an automatic focus control loop, and a retry search signal for searching the focusing position is caused to be generated by the search signal generation means, thereby, a refocusing control in case when an automatic focusing servo loop can not be maintained can be started from the positions ahead or back to the focus position causing to enter into the automatic focus control loop.
