Abstract
Digital optical tape archival storage systems and methods are disclosed. A digital optical tape recorder may simultaneously write data and two or more guide tracks onto a digital optical tape recording medium. A digital optical taper reader may include a camera comprising an array of detectors to capture a two-dimensional image of the digital optical tape recording medium, and an image processor to extract the data from the two-dimensional image. The camera may capture the two-dimensional image of the digital optical tape recording medium without aligning individual data bits recorded on the digital optical tape recording medium to individual detectors within the camera.
Claims15
A digital optical tape archival storage system comprising:
- a digital optical tape recorder configured to simultaneously write data and two or more guide tracks onto a digital optical tape recording medium;
- and
- a digital optical taper reader comprising:
- a camera comprising an array of detectors to capture a two-dimensional image of the digital optical tape recording medium, and
- an image processor to extract the data from the two-dimensional image,
- wherein the camera captures the two-dimensional image of the digital optical tape recording medium without one-to-one alignment of individual data bits recorded on the digital optical tape recording medium to individual detectors within the camera.
A digital optical tape recorder comprising:
- a spatial light modulator comprising a linear array of individually controllable elements to write a corresponding line of data bits onto the digital optical tape recording medium;
- a guide track generator to generate the two or more guide tracks;
- and
- a data combiner to combine data to be stored and the guide tracks such that each line of data bits written on the digital optical tape recording medium includes a block of data and a corresponding portion of each of the two or more guide tracks.
A method for archival data storage on a digital optical tape recording media, comprising:
- generating two or more guide tracks;
- combining data to be stored and the two or more guide tracks such that each line of data bits to be written on the digital optical tape recording medium includes a block of data and a corresponding portion of each of the two or more guide tracks;
- and
- writing each line of data bits onto the digital optical tape recording medium by modulating a light beam using a spatial light modulator having a corresponding linear array of individually controllable elements.
A digital optical taper reader comprising:
- a camera comprising an array of detectors to capture a two-dimensional image of a digital optical tape recording medium, and
- an image processor to extract the data from the two-dimensional image,
- wherein the camera captures the two-dimensional image of the digital optical tape recording medium without one-to-one alignment of individual data bits recorded on the digital optical tape recording medium to individual detectors within the camera.
