Tape manufacturing system
First Claim
1. A non-transparent tape useable as substrate in the manufacture of a high temperature superconducting conductor, said non-transparent tape comprising:
- (a) a surface finish of about 0.1 to about 10 nm RMS; and
(b) a surface defect area fraction of about 0.5% to about 10%.

Abstract
A tape manufacturing system and a tape-surface-inspection unit are disclosed. The tape-surface-inspection unit is capable of continuously characterizing the surface of a non-transparent tape that is usable with or without a tape manufacturing system. The tape-surface-inspection unit includes a surface illuminator, an imager, an image processor, a tape guide, and, optionally, an indexer. The surface illuminator provides a tape surface located by the tape guide in a manner that allows the imager to capture images for characterization by the image processor. The indexer facilitates a correlation of locations along the tape and a characterization of the locations on the tape. The tape manufacturing system, in addition to at least one tape-surface-inspection unit, includes a tape-processing unit, a tape handler, and a controller.
