Abstract: PROBLEM TO BE SOLVED: To provide an optical disk system in which a tilt of a head to a disk can be controlled so as to be automatically made small and further more gap control can be suitably performed even when surface deflection of the disk is generated and to provide its controlling method.
SOLUTION: In a feed-forward control section 15, a periodical surface deflection quantity of the rotated disk is estimated based on the tilt detected by a tilt sensor 28 and the distance between the optical head 5 and the rotated disk is controlled so as to be constant. In a tilt feed-back control section 16, the tilt of the optical head 5 is controlled so as to be nearly zero. Thereby, the tilt of the head can be controlled so as to be automatically reduced and a stable gap error signal can be obtained.

Abstract: PROBLEM TO BE SOLVED: To provide an electronic apparatus and an image display method of game apparatuses etc. capable of easily and clearly demonstrating the state of displayed objects to users without having to use a dedicated display part or superimposition and effectively using a display region. SOLUTION: In a game terminal for displaying characters through the use of polygons, an attribute information of a character such as "physical strength" is related to the number of polygons constituting the character and stored in a database. In the case of the occurrence of, for example, such an event as to "throw a punch" to the character, the attribute information of the character is altered according to the event, and the number of the polygons of the object is altered according to the alteration of the attribute information. It is thereby possible for a user to easily recognize changes in the attribute of the character by changes in the number of the polygons without having to use a dedicated display part.
