Patent ID: 8353257

Claim:
A deposition apparatus for depositing a superconducting layer on a tape, the deposition apparatus comprising: a supply reel having a guide groove portion with a tape wound around the guide groove portion to supply the tape upon rotation of the supply reel; a feed and deposition unit spaced apart from the supply reel; the feed and deposition unit including a cylindrical drum having a spiral guide groove formed around an outer circumference of the drum, and a plurality of guide rollers each having a plurality of guide grooves formed around an outer circumference of the roller, the guide grooves disposed at regular intervals and configured to take the tape therein and feed the tape upon rotation of the roller, said guide rollers spaced equidistantly apart from the drum and each guide roller inclined at a predetermined angle with respect to a rotating shaft of the drum and in parallel relation to one another such that the guide grooves of each guide roller are aligned to the guide grooves of another guide roller; and a collection reel spaced apart from the feed and deposition unit, the collection reel having a guide groove portion to wind and collect the tape therein upon rotation of the collection reel, wherein the supply reel is positioned at one lateral end side of the feed and deposition unit and inclined in a same inclined angle as the guide rollers are inclined with respect to the rotating shaft of the drum such that the guide groove portion of the supply reel is aligned to associated guide grooves of the guide rollers, said associated guide grooves located at said one lateral side of the feed and deposition unit and over which the tape feeds, to linearly guide the tape from the supply reel to the guide rollers and wind around an outer circumference of the guide rollers and drum in multiple turns without overlapping, wherein the collection reel is positioned at an opposite lateral end side of the feed and deposition unit and inclined in a same inclined angle as the guide rollers are inclined with respect to the rotating shaft of the drum such that the guide groove portion of the collection reel is aligned to associated guide grooves of the guide rollers, said associated guide grooves located at said opposite lateral side of the feed and deposition unit and over which the tape feeds, to linearly guide the tape from the guide rollers to the collection reel for winding thereon.
