To provide a rotating disk medium access interface device which can fast and continuously write and read the data while maintaining its connectivity to an existing host computer.
The file management information that is stored in a disk medium of a disk storage means 2 is previously copied to a memory means 3. When the data are read out of and written into the means 2, a 1st access means 4 accesses the means 3 to prepare its read/write operations. Then the data can be continuously transferred to the means 2 by a 2nd access means 5. Thus, the means 2 has no access of a head arm to a file management area that occurs every time the data are transferred for every cluster and can perform the fast and continuous transfer of data to a user data area.
