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： 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.
