Abstract
Digital optical tape archival storage systems and methods are disclosed. A digital optical tape recorder simultaneously writes data and two or more guide tracks onto an unformatted digital optical tape recording medium. A digital optical tape reader includes a camera and an image processor. The camera captures a two-dimensional image of the digital optical tape recording medium including the data and the two or more guide tracks. The image processor extracts the data from the two-dimensional image based, at least in part, on the guide tracks.
Claims10
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 an unformatted digital optical tape recording medium;
- and
- a digital optical tape reader comprising:
- a camera to capture a two-dimensional image of the digital optical tape recording medium including the data and the guide tracks, and
- an image processor to extract the data from the two-dimensional image based, at least in part, on the guide tracks.
A method for archival data storage on digital optical tape recording media, comprising:
- simultaneously writing data and two or more guide tracks onto an unformatted digital optical tape recording medium;
- and
- capturing a two-dimensional image of the digital optical tape recording medium with a camera, the two-dimensional image including the data and the two or more guide tracks, and
- processing the two-dimensional image to extract the data based, at least in part, on the guide tracks.
The method of claim 7, wherein
- the camera is configured to oversample the data such that a linear density of picture elements in the two-dimensional image captured by the camera is at least double a linear density of bits in the data recorded on the digital optical tape recording medium.
