Abstract
Disclosed is a belt driven tape cartridge capable of recording data at a higher density and a higher speed than in the conventional belt driven tape cartridges. The belt driven tape cartridge includes a flexible non-magnetic support, a magnetic recording layer formed on one surface of the flexible support and having a surface roughness of 10 nm or under, and a back coat layer formed on the other surface of the flexible support and having a surface roughness being above 100 nm but under 300 nm.
Claims4
A belt driven tape cartridge comprising:
- a box body;
- a magnetic recording tape including a flexible non-magnetic support, a magnetic recording layer formed on one surface of said flexible support and having a surface roughness being 10 nm or under, and a back coat layer formed on other surface of said flexible support and having a surface roughness being not less than 100 nm but not more than 300 nm;
- a pair of tape reel hubs, provided within said box body, for winding up and accommodating said magnetic recording tape;
- magnetic recording tape guide members for determining a path for said magnetic recording tape between said pair of tape reel hubs so that said magnetic recording tape passes near a front surface of said box body;
- and
- drive belt holding members for holding a drive belt within said box body in a state that the drive belt is perpetually kept in pressure-contact with said magnetic recording tape wound on both of said pair of tape reel hubs and is capable of being driven from the front surface of said box body.
