The buffer administrative use table where the buffer territory which corresponds vis-a-vis the sector shows which is provided. With this table, buffer expedient (RAM), it sets with the joint ownership buffer territory to which the plural sectors use the same buffer territory and the individual buffer territory to which the sector corresponds individually. And, the flag which shows the processing circumstance of the data in each sector is provided. Because of this, in combination with the lead/read of USB-FDD/the light/write to usage condition, as it does in high speed, it decreases the capacity of the RAM buffer. In addition, the territory of the RAM buffer which is used for the lead/read of that data/the light/write, usage condition and other use together, is made degree of necessary the adjustment possible.
