    摘要： Various embodiments herein include one or more of systems, methods, software, and/or data structures to test and evaluate unformatted optical media such as optical tape and optical discs. Advantageously, testing and evaluation can be performed earlier in the manufacturing process of the optical media to locate defects and/or other problems or issues with the optical media that can be addressed before additional manufacturing steps are performed and possible wasted. The systems and methods include at least two optical pickup units (OPUs), a first of which may be dedicated to writing digital data and the second of which may be dedicated to scanning, locating, tracking and/or reading the written data (when the optical media is moving in a first direction) in one of a plurality of manners. Information (e.g., optical signals such as sum, differential push pull and focus error signals) associated with the writing, scanning and retrieving of data at one or more locations or segments of the optical media may be used part of an analysis of one or more properties (e.g., signal to noise, signal jitter, thickness, roughness) of the optical media.

    摘要： In one example, a method is provided for detecting the relative position of a transducer head with respect to a storage medium utilizing existing or previously written data structures on a magnetic storage tape and optically diffractive media. The method includes generating a read signal from a read element associated with a transducer head, the read signal generated from a reference data track stored on a magnetic storage medium, and determining a relative position of a first diffractive medium with respect to a second diffractive medium, wherein the first diffractive medium is associated with the storage medium. The transducer head is repositioned relative to the storage medium in response to the read signal and the relative position of the first diffractive medium and the second diffractive medium.

    摘要： According to one aspect, methods and systems for determining the position of a recording head using existing data structures on magnetic storage media are provided. In one example, a recording head writes data to an active track on a magnetic storage tape, the recording head including a write element and a read element in a known spatial relationship, wherein the read element is configured to access at least a portion of a reference track when the write element is accessing the active track. A controller determines a relative position of the transducer element to the reference track and repositions the recording head to write data to the active track. The read element may be a backward channel reader or dedicated read element of the recording head for reading reference tracks during read and/or write operations.

    摘要： Systems and methods for data storage on an optical medium having a plurality of tracks include splitting a light beam into a higher power main beam and at least one lower power side beam that form corresponding spots spaced along a selected one of the plurality of tracks and selectively positioning and aligning the beams/spots along the selected one of the plurality of tracks using the higher power main beam to write data while reading previously written data using the at least one lower power side beam. The systems and methods may include correlating the read signal with a time-shifted write signal to provide a direct read after write capability to verify data written to the optical medium. In one embodiment, an optical tape drive includes an optical pickup unit (OPU) that generates a lower power satellite beam to read data directly after writing by a higher power main beam.
