摘要： The present invention relates to a photographic information setting device having a switch arranged to turn on and off and generate digital data when a stepwise operating member changes its position, wherein the turning on and off of the switch is detected with the help of current supply to the switch to renew the digital data until a desired value of any exposure factor is preset. In the present invention, when the aforesaid stepwise operating member lies in any of click-stopped positions, the current supply to the switch is cut off to prevent wasteful consumption of electrical energy. The number of times of turning on and off of the switch is once stored in a counter, and, upon detection of turning on and off of the switch, a computer reads out the content of the counter so that the renewed digital data are formed in the interior of the computer.

摘要： A mechanism for compensating the servo data in a disk storage drive is provided. On each recording surface of a disk, a plurality of servo regions are diametrally formed in data regions along the diametral direction of the disk. In the servo region, a gray code (cyclic binary code) representing the address of a data track is recorded so as to correspond to the data track, and a burst pattern as a signal for positioning the head on the track are recorded. In the data track region, tracks are formed at a predetermined pitch P and in the tracks, a plurality of data is recorded. ID (Identification) is the identification information of the individual data. A servo compensation signal region is formed at a position sandwiched by the data region and the servo region known as the write recovery area. This is to compensate the servo signal in the servo region, thereby to enable error recovery when a read error or the like occurs in the servo region.
