摘要： A method and an optical storage medium are provided for storing data to and accessing data from an embedded virtual medium within the optical storage medium. Information describing the embedded virtual medium may be stored on to the optical storage medium. Space for an embedded lead-in area of the embedded virtual medium, as well as user data for the embedded virtual medium, may be allocated within a data zone of the optical medium. A spare sector bitmap may be included in a lead-an area of the optical medium indicating spare sectors within the embedded virtual medium as being unavailable. A spare sector bitmap may be included within the embedded virtual medium indicating available spare sectors of the embedded virtual medium. Physical sector/logical block mapping of the optical storage medium may be modified for accessing data stored on the embedded virtual medium.

摘要： An application on a computing device to write data to a storage medium associated therewith. The data is to be written to a secure storage area associated with an object on the storage medium, and the secure storage area has a value storage area associated therewith. The application generates a nonce and employs a shared session key (KS) to encrypt the nonce to result in (KS(nonce)). The storage medium receives same and decrypts with (KS) to result in the nonce, locates the value storage area associated with the secure storage area, and stores such nonce in the located value storage area. The application employs the nonce to generate a key (KH), encrypts the data with (KH) to result in (KH(data)), and sends same to the storage medium for storage in the secure storage area. Thus, (KH(data)) is associated with the nonce in the value storage area.
