Abstract: Among a plurality of communication formats to be used to transmit data with a predetermined period, a communication format that requires equal to or greater than half the period to transmit data is defined as a normal format, and a communication format that requires smaller than the half the period to transmit data is defined as a time division format. An antenna wirelessly receives data from the target device. A reception control circuit controls a directional direction of the antenna to measure states of electric waves around the wireless communication device. In a case that a direction of the target device is indistinguishable from a direction of the non-target device as a result of measurement of the states of the electric waves, the reception control circuit changes a communication format of the wireless communication device from the normal format to the time division format.

Abstract: An optical recording/reproducing apparatus effects a seek operation by moving an optical pick-up, which includes an objective lens for projecting a light spot onto an optical card, in a tracking direction perpendicular to the track direction over a desired distance between a current track on which the light spot is currently made incident and a desired track on which the light spot is to be made incident next. To reduce the access time during a seek operation, the vibration of the optical card is monitored and the tracking control is started substantially immediately when the light spot is just made incident upon the desired track. The tracking control may be initiated, e.g., at a timing which is separated from a peak of the vibration by 1/4 of a period of the vibration. Alternatively, the tracking control may be started when the acceleration of the vibration becomes zero.
