• wherein said storage device system comprises:
• a plurality of signal transmission paths connected respectively to the plurality of installed storage devices;
• and
• a plurality of system side communications sections for transmitting and receiving signals respectively to and from said plurality of storage devices, via said plurality of signal transmission paths;
• the following steps (A) to (C) are implemented for each signal transmission path;
• (A) a step of inputting a signal exchanged between a storage device and a system side communications section;
• (B) a step of correcting said input signal on the basis of a previously set correction parameter;
• and
• (C) a step of outputting the corrected signal;
• and
• said correction parameter is a value established on the basis of any one of a length of the signal transmission path, a wavelength attribute of said input signal, and a storage device attribute relating to the storage device.
