摘要： An optical storage system includes an optical head configured to split a light beam into a higher power main beam and at least one lower power side beam. The optical storage system also includes a controller configured to alter an optical medium, via modulation of the higher power main beam according to a writing strategy waveform that defines at least n pulses for every n bits of data to be written to the medium, while processing a first signal resulting from the at least one lower power side beam being reflected from the medium and a second signal indicative of the writing strategy waveform to remove noise from the first signal caused by the higher power main beam to generate output indicative of the data directly after writing.

摘要： In at least one embodiment, an optical data storage tape is provided. The optical data storage tape includes a read/write data area including a plurality of writeable tracks for storing data thereon, each writeable track having a first track width. The optical data storage tape further includes a seam area positioned proximate to the read/write data area. The seam area including a plurality of non-writeable tracks, each non-writeable track including a second track width that is greater than the first track width for each writeable track.

摘要： 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.

摘要： 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.
