ABSTRACT:
To guarantee a data transfer rate irrespective of a performance of a memory card.A parameter to show a data transfer efficiency is previously recorded in a recording medium101in which data is written per data size that can be increased and decreased stepwise and the data transfer efficiency is variable in accordance with the data size. Next, a data accessing apparatus105issues a parameter acquisition command to the recording medium101. The recording medium101which received the parameter acquisition command transmits the parameter. The data accessing apparatus105collates the received parameter with the data transfer efficiency required in the data to be written/read to thereby select an optimum data size. Then, the data accessing apparatus105writes/reads the data to the recording medium101based on the selected optimum data size.
