Patent ID: 8180950

Claim:
A method to manage information, comprising the steps of: supplying an optical and holographic information storage medium consisting of an optical data storage layer formed in a substrate and encoding one or more alert messages, a first gap layer disposed over said data storage layer, a dichroic mirror disposed over said gap layer, a second gap layer disposed over said dichroic mirror, a holographic data storage layer disposed over said second gap layer, and a cover layer disposed over said holographic data storage layer; supplying an optical and holographic drive assembly comprising a drive controller, a drive servo mechanism comprising a drive servo in communication with said drive controller and a rotatable shaft wherein said drive servo rotates said rotatable shaft thereby causing said optical and holographic information storage medium to rotate, a solenoid in communication with said drive controller, a member slidably disposed within a tubular member, wherein said tubular member is slidably disposed within said solenoid wherein a first lasing device, a second lasing device, a reflective spatial light modulator, an optical sensor, and a beam splitter are disposed on said member, wherein said drive controller causes said optical sensor to rotate at the same rotation rate as said optical and holographic information storage medium, and wherein said beam splitter receives laser light from said first lasing device and directs a carrier beam in a first direction toward said reflective spatial light modulator and a reference beam in a second direction, wherein said first direction differs from said second direction; reading information from said optical data storage layer before reading data from, or writing data to, said holographic data storage layer.
