1. Field of the Invention
The present invention generally relates to a method for directly writing data into an optic disk without a computer system; and in particular to a method for directly writing data retrieved from an electronic data storage into an optic disk without a computer system interfacing therebetween.
2. The Related Art
With the rapid development and prevalence of electronic storages, such as compact flash memory, more and more data are stored in the electronic storage for portability and fast access. To more space-efficiently store the data, some people prefer to transfer the data from the electronic storage to optic disks for data backup purposes. Heretofore, the optic disk drive must be connected to a computer system for data writing operation. Thus, the data have to be read into the computer system and then written by the computer system into the optic disk accessed by means of the optic disk drive. This causes problems. For example, a computer system is a must in transferring data from a portable compact flash memory device to an optic disk. Thus, such a data transfer operation cannot be carried out without a computer system having proper data ports.
Thus, the present invention is aimed to solve the above problem by providing a method for directly transferring data from a compact flash memory device to an optic disk without a computer system interfacing therebetween.
Accordingly, an object of the present invention is to provide a method for writing data retrieved from an electronic storage to an optic disk without a computer system interfacing therebetween.
Another object of the present invention is to provide an optic disk drive capable to perform a direct writing operation to an optic disk without being controlled by a computer system.
To achieve the above objects, in accordance with the present invention, there is provided a method for directly writing data into an optic disk that is performed by an optic disk drive incorporating a control unit to which an external data storage device, such as compact flash memory device, is connected. The method comprises steps of (1) initiating a writing operation, (2) setting the optic disk drive to busy condition, (3) checking if an optic disk is properly loaded and if the external memory device is correctly connected, (4) checking if the optic disk is a UDF disk; (5) issuing a warning, if it is not, (6) creating a folder in the optic disk, (7) retrieving data from the external data storage device and writing the data into the folder of the optic disk, and (8) ending the writing operation. No computer-based interface is required between the optic disk drive and the external data storage device in performing the data writing operation.
