摘要： A small form factor optical disk drive is provided that incorporates a SIL/objective lens assembly. A laser for the small form factor optical disk drive has a coherence function having maxima spaced apart by intervals. The optical disk drive is configured such that a roundtrip optical path through the SIL/objective lens assembly is such that a coherence value for the laser is located in one of the intervals.

摘要： An optical storage disc has portions for storing pre-recorded or mastered information and portions for storing user writable information, where the mastered portion and the writable portions have different storage capacities or areal data densities. During manufacture, a substrate is formed with a sequence of bumps to represent the mastered information and a series of grooves and lands, where information can later be written on the lands. A phase-change material is deposited over the substrate, the phase-change material changing both physical structure and optical constants when written to, e.g., by a laser.

摘要： The present invention relates to digital rights management (DRM) for content that downloaded and saved to a storage device. The storage may be a disk drive, or network attached storage. In addition, the storage device performs cryptographic operations and provides a root of trust. The DRM employs a binding key, a content key, and an access key. The binding key binds the content to a specific storage and is based on a key that is concealed on the storage. The binding key is not stored on the storage device with the content. The content key is a key that has been assigned to the content. The access key is determined based on a cryptographic combination of the content key and the binding key. In one embodiment, the content is provisioned based on the access key and stored in encrypted form in the storage device.

摘要： In accordance with one aspect of the invention, a system is provided that includes a database configured to store data according to a first encryption protocol such as an FDE HDD protocol. The data provided to the database is encrypted according to a second encryption protocol such as an AES protocol. A user selects a desired video through a server coupled to the database. Upon payment and selection by the user, a manager provides the a first key to the database so that the first encryption may be stripped from the selected video. The server couples to a remote content key server to obtain a second key to remove the second type of encryption. The resulting decrypted digitized video may then be burned to a DVD disc for distribution to the user.

摘要： A block-level storage device is provided that implements a digital rights management (DRM) system. In response to receiving a public key from an associated host system, the storage device challenges the host system to prove it has the corresponding private key to establish trust. This trust is established by encrypting a secure session key using the public key. The host system uses its private key to recover the secure session key. The storage device may store content that has been encrypted according to a content key. In addition, the storage device may encrypt the content key using the secure session key.

摘要： A first surface optical disk is disclosed that has machine readable code information, such as bar code information, disposed thereon to permit a disk drive or other device to obtain certain basic information regarding the disk in an efficient and reliable manner. The machine readable code may include error detection and error correction code to correct errors, such as those caused by surface dust, that may arise during reading the machine readable code. The machine readable code may be disposed within a portion of a ring on the optical disk. Human readable alphanumeric characters, including graphics, identifying the side of the optical disk and other basic information may also be disposed within the ring.
