Apparatuses, products, devices and methods of manufacture consistent with the invention include optically readable media with at least one mechanism, chemical, agent, and/or process for limiting the time period that at least a portion of encoded information can be read and/or accessed by an optical beam and/or reader capable of reading the encoded information.

Optical media, read inhibiting agents and methods of making and using same

A data storage device comprises a first substrate and a second substrate, wherein at least the first substrate has defined thereon a plurality of pits and lands covered by a reflective material; and a bonding layer between the first and second substrates including a reactive agent that interferes with the passage of light in response to predetermined stimulus. In another embodiment, an optically-readable storage media, comprises a substrate having encoded data stored thereon, a reactive agent that, in response to predetermined stimulus, interferes with the passage of light of a predetermined frequency range, and a second reactive agent that, in response to predetermined stimulus, degrades the readability of the encoded data.

Limited play optical devices with interstitial reactive layer and methods of making same

Methods and apparatus are provided for making an optically readable storage media in which the reading beam passes through a bonding layer configured with a reactive material that transforms from an optically transparent state to an optically opaque state after exposure to a predefined stimulus, thereby inhibiting access to the data encoded on the optically readable storage media. The method includes steps of synthesizing a blocked dye combining the blocked dye with a carrier material curing the resultant combination deblocking the dye to produce a reduced dye in the resultant bonding layer exposing the optically readable storage media with the reactive material in its bonding layer to a predetermined stimulus. In a further aspect of the present invention methods and apparatus are provided for making an optically readable storage media wherein the reading light passes through the bonding layer and the data encoded information is encoded on the Lsubstrate. In yet another aspect of the present invention methods and apparatus are provided for making an optically readable storage media with at least two mechanisms for limiting access to the encoded data of the optically readable storage media.

A system and method cure a resin disposed between a combination of a top substrate and a bottom substrate with low power. One of the top and bottom substrates includes metallized data pits. Resin-curing light is directed at sides of the data pits.

System for forming bonded storage disks with low power light assembly

An improved substrate and stamper holder and method of forming substrates are disclosed. According to a preferred embodiment of the invention, a substrate for a DVD has a moat with a capillary barrier shape. Under one embodiment, the moat has a region with an abrupt outer diameter transition. One embodiment has the outer diameter transition at approximately at a right angle relative to a registering surface of the substrate. Another embodiment of the invention provides a wider moats. The improvements reduce the likelihood of resin wicking past the moats.

Substrate design for bonded storage disks and method of making same

A system and method distribute a resin disposed between a top substrate and a bottom substrate. Each substrate has a center hole, and the top and bottom substrates and the resin define an interior region. A top substrate assembly forms a seal over the center hole of the top substrate and creates a vacuum at the interior region. A bottom substrate assembly receives the top and bottom substrates with the resin disposed in-between. A spinning assembly causes the top and bottom substrates to spin according to a predetermined spin profile.

System and method for distributing a resin disposed between a top substrate and a bottom substrate

A system and method dispense resin between substrates. A top substrate device holds a top substrate concave up. A bottom substrate device holds a bottom substrate concave down. A resin dispensing device has a needle and dispenses a trajectory of resin defined by an arc having a tangent that touches a tangent of a concave-up-shaped top substrate. The top substrate device may be arranged to include a dampening mechanism to cause a dampened release of the top substrate. Moreover, the top substrate device may be arranged to hold a top substrate so that the top substrate has a continuous concave-up shape extending from a center portion of the top substrate to its outer diameter, and the bottom substrate device may be arranged to hold a bottom substrate so that the bottom substrate has a continuous concave-down shape extending from a center portion of the bottom substrate to its outer diameter.

A vacuum-metallizing machine including a metal platter base (17) having an obverse side and a face side. A substrate-receiving platter (2) is resiliently disposed (3, 3b) in a recess on the face side of the platter base (17). The platter (2) receives a substrate to be metallized. A circumferentially-arranged rigid ring (27) of predetermined dimensions and location is disposed on the face side and mates with a ring (29) around a port (11) on the wall of the vacuum chamber which surrounds an opening in the wall. Engagement of these rings aligns the platter base (17) relative to the port (11, 12, 13 and 14). A compliant ring (42) is disposed between the wall and the platter base (17). The obverse side of the platter base (17) and the chamber are resiliently forced (37a, 37b, 37c) into contact with each other with a toggling action (24, 22b, 22) whereby to align the platter base (17) relative to the port, to force the outer diameter of the platter base (17) into metal-to-metal contact with the periphery of the port (11), to align the substrate relative to the port (11) and also to force the compliant ring into sealing engagement with the wall, thus, to form a vacuum tight seal.
