The game install media uses a traditional DVD-ROM disk (probably double layered). You are able to read the content of the disc if you have the disk media, but without keychip and main application, it is unknown if you can dump the contents.
Hatsune Miku Project Diva Arcade Future Tone
The DVD patch I acquired is for one version of the game, and it contains the following files.

After checking against DVD for another version of the game, it looks like SEGA NU (ALL P-ras) DVD-ROM SYSTEM uses the following files as install:
AAV_0039.70.01_20150428165732_0.pack
AAV stands for the Nu-series machines based on: SegaTools, it is also the start of the serial number of the machine.
DISC_01_03
This looks like an empty file that is used to indicate which disc this is for. The pack I have at hand has total of 3 discs, and the second disc include a file DISC_02_03
SBZV_AAV.icf
This file's purpose is still unknown, could be some special config for game on this system.
SBZV_5.00.02_20150529201945_0_0_29234.app
SBZV stands for Hatsune Miku Project Diva Arcade Future Tone, this matches with the code on my keychip, this could include the game image. 5.00.02 is probably the version number of the game.
