Magnetic tape splicing for reducing tape pack distortion
First Claim
1. A pack of magnetic recording tape comprising:
- a reel hub;
a leader secured to the reel hub;
a web of magnetic recording tape having an elongated dimension;
a splicing tape which secures the web to the leader, the splicing tape having a length L parallel to the elongate dimension of the web, the length L being on the order of Nπ
D, where D is the diameter of the reel hub and N is an integer.

Abstract
A pack of magnetic recording tape (100) comprises a splicing tape (120) which adheres a web of a magnetic tape (122) to a leader (124). The leader (124) attaches to a reel hub (126) around which the tape is to be wound. The length L of the splicing tape in a direction parallel to an elongate dimension (127) of the magnetic tape is on the order of NπD, where D is the diameter of reel hub and N is an integer. In one embodiment, the length L of splicing tape is just slightly less than the circumference of the reel hub. The tape assembly comprising the combination of the magnetic tape, the leader, and the splicing tape greatly reduces the amount of permanent tape deformation, and provides a more efficient tape pack with smaller discontinuities. Consequentially, the stress on the magnetic tape is greatly reduced, which reduces the amount of permanent deformation and the number of magnetic tape layers that are affected by the deformations. This minimizes the area of the magnetic tape that may be rendered unusable. The tape pack (100) can be utilized in a magnetic tape cassette or cartridge (140), which can be either a dual reel cartridge or a single reel cartridge.
