Embodiment Construction

[0093] Optical strip technology, manufacturing, and applications can be highly interconnected to achieve the cost, performance, density, and other goals required to provide a commercially viable solution. Goals such as reducing manufacturing costs while producing reliable, high-quality optical tape may require substantial innovations in manufacturing technology methods as well as systems. Substantial innovations in optical tape technology and manufacturing methods and systems may be required to produce optical tape that supports high-density storage and high performance. Thus, the methods and systems disclosed herein for manufacturing optical tapes can be used to manufacture the optical tapes disclosed herein, and the methods and systems disclosed herein for using optical tapes can be used to use the optical tapes disclosed herein.

[0094] Aspects of optical tape technology, optical tape manufacture, and optical tape use are disclosed herein. Methods and systems of optical t...

Abstract

The invention relates to a 'jump gap' servo mode provided to position an optical tape medium relative to a pickup head so that tracking may be reestablished after gaps in the servo tracks which occur in the pre- and post-amble fields. These gaps arise periodically because of a seam in the drum used to emboss the servo track on the tape medium. Also disclosed herein are other aspects of optical tape technology, tape manufacturing, and tape usage including: configurations, formulations, markings, and structure of the optical tape; manufacturing methods, systems, and apparatus including curing processes, coating methods, embossing, drums, testing, tracking alignment stamper strip; pick up head adapted for the disclosed optical tape; and optical tape uses including optical storage media devices for multimedia applications.

Description

Background technique [0001] The optical pickup unit may not be able to maintain focus on certain imperfections in the optical media. Contents of the invention [0002] Aspects of optical tape technology, optical tape manufacture, and optical tape use are disclosed herein. Methods and systems for optical tape technology Disclosed are optical tape media, including configurations, compositions, markings, and structures; optical tape manufacturing methods, systems, and apparatus. Methods and systems include: curing processes, coating methods, embossing, drums, Testing, tracking and aligning stamper strips; optical tape methods and systems including: pick-up heads for the disclosed optical tapes; and optical tape uses including optical storage media devices for multimedia applications. [0003] A data storage system may include an optical medium having a defect and a plurality of tracks on each side of the defect exhibiting (i) a modulated wobble field next to the defect represe...
