An optical storage system includes an optical head and a controller. The optical head is configured to split a light beam into a higher power main beam and a lower power side beam. The controller is configured to write data to an optical medium via the higher power main beam, and read, directly after writing, feedback from the optical medium containing the written data and noise caused by the higher power main beam. The controller is also configured to process the feedback using data indicative of the higher power main beam to remove the noise and generate output indicative of the written data, and automatically adjust a delay of the feedback or the data indicative of the higher power main beam based on a signal quality of the output.

An optical storage system includes an optical head and controller arrangement. The arrangement is configured to write data to an optical medium via a higher power main beam, to read, directly after writing, feedback from the medium containing the written data and noise resulting from the higher power main beam, to remove the noise from the feedback by dividing the feedback with data indicative of the higher power main beam, and to generate output indicative of the written data.

An optical storage system includes an optical head configured to split a light beam into a higher power main beam and a lower power side beam. The system also includes a controller. The controller is configured to modulate the higher power main beam according to writing commands to write to an optical medium while processing first data resulting from the lower power side beam being reflected from the medium and second data obtained from a look-up table that maps the writing commands to digital representations of filtered writing strategy waveforms to remove noise from the first data caused by the higher power main beam and generate output indicative of written data directly after writing.

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.

Methods and apparatus for archival storage of an image are disclosed. The image is converted into one or more bit plane images. Fiducial markers are generated and written onto digital optical tape concurrent with writing the one or more bit plane images onto the digital optical tape.

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.

Disclosed is storage device implemented as an optical tape and having layers. A substrate layer provides resilience to the storage device while a recording stack layer is capable of being inscribed with human-readable information. An optional lubricant layer reduces strain on the storage device as it is both inscribed and read. An optical tape records human-readable information in a small physical area and in a durable medium.
