PURPOSE:To efficiently perform the development and management of a user program and data, by providing both a reproduction-only area where software is recorded in advance, and a rewrite area where the user program and the data can be written on a sheet of optical disk. CONSTITUTION:Both the rewrite area 2 where reproduction, recording, and erasure are performed by projecting a laser beam and the reproduction-only area 1 where information not being erased by the projection of the laser beam are provided on a sheet of optical disk. In the reproduction-only area 1, map information, dictionary information, and the software such as the operating system of a computer, etc., are recorded as on-going softwares. In the rewrite area 2, the data or a program generated by a user properly is recorded. In such a way, it is possible to perform the operation of the data or the development and the management of the program by the user only by using a sheet of disk. |
