The present invention relates to a memory drive that can be virtualized as an optical disk drive and a virtualizing method thereof. One embodiment of the present invention discloses a method for virtualizing a memory drive as an optical disk drive, the memory drive comprising a storage memory and a storage memory controller, which reads or writes data from and to the storage memory. Therefore, according to one embodiment of the present invention, a solid-state which comprises a flash memory and a flash memory controller can be used like an optical disk.

Memory drive that can be operated like optical disk drive and method for virtualizing memory drive as optical disk drive

Provided are a method for emulating a separate contents memory unit into an optical disk, an optical disk drive using the same, and an optical disk including a security zone. In the method, when an optical disk processing command from a host is present, whether an optical disk is present in the optical disk drive is judged. When the optical disk is not present in the optical disk drive as a result of the judgment, the contents memory unit is executed as a virtual optical disk. An application stored in the contents memory unit is displayed. The optical disk drive includes an optical disk storage unit, a contents memory unit, and a controller. The optical disk storage unit stores or reproduces contents using an optical disk. The contents memory unit stores contents therein and is executed as a virtual optical disk when the optical disk is not present. The controller controls the optical disk storage unit and the contents memory unit, and controls an access to be made, subject to the contents memory unit. The optical disk includes a fake zone that is accessible by all users without an authentication procedure, and a security zone that is accessible through the authentication procedure. Accordingly, a user can receive and use desired contents using the optical disk drive even when a disk is not present.
