Claim Text:
1. An information processing device, comprising: an emulated media drive established on a client, the emulated drive emulating a physical media drive configured to read a physical medium containing data stored in a compressed data storage range and data stored in an uncompressed data storage range; a receiving unit of the emulated drive, the receiving unit being configured to receive, from an emulated central processing unit, a reading instruction to read the medium, and to cause the instruction to function as an instruction to read an image file of the medium, the image file being stored at an image file storage range on an external storage device of a server, the server being connected to the client via a network; a data obtaining unit of the emulated drive, the data obtaining unit being configured to obtain data of the image file from a designated range of the image file storage range, the designated range being designated by the medium reading instruction; a determination unit of the emulated drive, the determination unit being configured to determine whether the designated range is within the compressed data storage range or the uncompressed data storage range; and a data output unit of the emulated drive, the data output unit being configured to output the obtained data to the emulated central processing unit, wherein when the medium reading instruction designates a designated range that is within the compressed data storage range, the data obtaining unit obtains the data stored in the compressed data storage range of the image file storage range, the determination unit determines that the designated range is within the compressed data storage range, and the data output unit first expands the obtained data and then outputs the obtained data; and wherein when the medium reading instruction designates a designated range that is within the uncompressed data storage range, the data obtaining unit obtains the data stored in the uncompressed data storage range of the image file storage range, the determination unit determines that the designated storage range is within the uncompressed data storage range, and the data output unit outputs the obtained data without first expanding the data.
