A disk controlling apparatus creates sense data indicating the contents of an error and writes it into an intermediate buffer provided within the disk controlling apparatus together with the record normally read when a key portion or a data portion constituting a record is not normally read. The disk controlling apparatus searches the intermediate buffer for desired record, reads and informs an error while taking the sense data into consideration for each record. The disk controlling apparatus stores a write address in a memory at the time of writing data, and when data are normally written the write address is eliminated from the memory, while holding the address when data are not normally written. At the time of reading data, if the address which agrees with the read address is stored in the memory, the disk controlling apparatus reports an error to a host apparatus. The disk controlling apparatus further calculates the busy ratio indicating the rate at which each channel adapters is used for I/O processing, and data is transmitted and received to and from the host apparatus through the channel adapter which has the lowest busy ratio.

The call toll processing method comprises a calling party toll data input step wherein calling party toll data is input from a toll processing data table that stores calling party toll data determined on the basis of data regarding the distance from the originating subscriber to the originating exchange accommodating the originating subscriber, a location data extraction step wherein location data relating to the terminating exchange accommodating the terminating subscriber having the dialed number input by the originating subscriber is extracted from dialing data, a called party toll data input step wherein called party toll data determined on the basis of data regarding the distance from the terminating subscriber to the terminating exchange is input from the terminating exchange, and a call toll computation step wherein call tolls between the originating subscriber and the terminating subscriber are computed on the basis of at least calling party toll data input in the calling party toll data input step, location data extracted in the location data extraction step, and calling party toll data input in the called party toll data input step.
