Abstract
Official abstract text for this publication.
There is provided a reel, the reel in which a difference in winding radii across the entire recording tape width between a winding terminal end of a first turn and a winding start end of a second turn of a recording tape that has been wound around a hub is 1.3 times a thickness of the recording tape, or less.
First claim
Opening claim text (preview).
What is claimed is: 1 . A reel, wherein: a difference in winding radii across the entire recording tape width between a winding terminal end of a first turn and a winding start end of a second turn of a recording tape that has been wound around a hub is 1.3 times a thickness of the recording tape, or less. 2 . A reel, wherein: an end portion of a recording tape is adhered to a hub by interposing abraded powder; and a difference in winding radii across the entire recording tape width between a winding terminal end of a first turn, and a winding start end of a second turn of the recording tape that has been wound around the hub is 1.3 times the thickness of the recording tape, or less. 3 . The reel of claim 1 , wherein an end portion of the recording tape is adhered to the hub without being coated with a liquid for adhering. 4 . The reel of claim 1 , wherein the thickness of the recording tape is 5.5 μm or less. 5 . The reel of claim 2 , wherein the thickness of the recording tape is 5.5 μm or less. 6 . The reel of claim 3 , wherein the thickness of the recording tape is 5.5 μm or less.
