Abstract
Data storage tape includes a substrate having a first side and a second side opposite the first side, a recording layer disposed on the first side of the substrate, and a coating disposed on the second side of the substrate. A surface of the coating has a pattern formed therein such that the pattern communicates with at least one of a first edge and a second edge of the data storage tape.
Claims22
Data storage tape having a first edge and a second edge opposite the first edge, the data storage tape comprising:
- a substrate having a first side and a second side opposite the first side, wherein the second side of the substrate has a pattern formed therein;
- a substantially uniform recording layer disposed on the first side of the substrate;
- and
- a coating disposed on the second side of the substrate, wherein the coating conforms to the pattern in the second side of the substrate to form the pattern in a surface of the coating,
- wherein the pattern communicates with at least one of the first edge and the second edge of the data storage tape.
A method of forming data storage tape, the method comprising:
- providing a substrate having a first side and a second side opposite the first side;
- forming a pattern in the second side of the substrate;
- disposing a recording layer on the first side of the substrate, including forming a substantially uniform surface of the data storage tape;
- and
- disposing a coating on the second side of the substrate, including conforming the coating to the pattern in the second side of the substrate and forming the pattern in a surface of the coating,
- wherein the pattern communicates with at least one of a first edge and a second edge of the data storage tape.
A method of coiling data storage tape, the method comprising:
- winding the data storage tape around a reel, including contacting a first side of the data storage tape with a second side of the data storage tape, the first side of the data storage tape including a substantially uniform recording layer and the second side of the data storage tape including a coating;
- and
- dissipating air entrapped between the first side and the second side of the data storage tape, including directing the entrapped air to at least one of a first edge and a second edge of the data storage tape with a pattern defined in the second side of the data storage tape and communicated with the at least one of the first edge and the second edge of the data storage tape,
- wherein the pattern is formed in a substrate of the data storage tape and the coating conforms to the pattern in the substrate to form the pattern in a surface of the coating.
