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.

A digital optical tape
- reader comprising:
- a camera to capture a two-dimensional image of a digital optical tape recording medium including data and two or more guide tracks, wherein the guide tracks include fiducial markers along a length of the digital optical tape recording medium, and
- an image processor to:
- estimate positions of the fiducial markers in the two-dimensional image captured by the camera,
- define a local coordinate system based on the estimated positions of the fiducial markers, and
- extract the data based on the defined coordinate system.
A method for retrieving data from a digital optical tape recording media, comprising:
- capturing a two-dimensional image of the digital optical tape recording medium with a camera, the two-dimensional image including the data and two or more guide tracks, wherein the guide tracks include fiducial markers along a length of the digital optical tape recording medium,
- estimating the positions of the fiducial markers in the two-dimensional image captured by the camera,
- defining a local coordinate system based on the estimated positions of the fiducial markers, and
- extracting the data based on the defined coordinate system.
