A storage medium is provided having a relatively large number of relatively small servo sectors. The processing station includes a chamber divider which divides the target chamber into upstream and downstream regions during charged particle beam processing of the target, the target being located in the downstream region. The coupling member may be selectively operationally coupled between the pair of electrical cables. Therefore, this solid-state image pickup device can achieve an arbitrary decimation rate and easily change a frame rate, resolution or the like only by changing drive conditions without making a complicated wiring structure of vertical transfer electrodes. The invention is based on using a combination pricing plan as response to a number of different charging requests, and determining the charging by said combination pricing plan, by using during the end user session different proxy components to identify service requests according to different service identification request rules, each proxy component using individual service identification rules.
