Claims

[Claim for Utility Model Registration] Information is read out sector by sector from a disk storage medium in which an information storage area is divided into a plurality of tracks in the radial direction, and each track is further divided into a plurality of sectors in the circumferential direction, and information is transmitted to an external device. In the disk memory device to be transferred, there is a memory means for temporarily storing information read from the disk storage medium, a transfer means for transferring the read information to an external device, and an information read command in sector units from the external device. The information in the sector specified by the read command is read from the disk storage medium and transferred to the external device by the transfer means, and the read end information is transferred, and the information is read from the sector next to the sector specified by the read command. The information up to the last sector of the track including the sector is read and stored in the memory means, and in response to an information read command to a sector subsequent to the first specified sector, the corresponding sector stored in the memory means is read out and stored in the memory means. and control means for reading out the information and causing the transfer means to transfer the information to an external device.
