Abstract

PURPOSE:To enhance a rquired tension characteristic, a durability life, and the characteristics of wow, flutter and jitter, by providing a material or a fabric having suitable warps and wefts. CONSTITUTION:A fabric of Calico hollow-weaven type is used as a core material having polyesther span yarns as warps 1 and nylon-66 sawing yarns as wefts 2. Further, the aspect ratio of used yarns is less than 1/2. The thus formed core material is coated on the outer surface thereof with antistatic synthetic rubber 3 or antistatic chloroprane or polyurethane so that a belt 4 is completed.

およびジッター特性などに種々の問題を含んでいる。Conventional flat belts used in disk drive devices do not have mechanical and transmission characteristics that meet the requirements of disks, especially anti-static properties, friction and
There are various problems in wear characteristics, durability characteristics, tension characteristics, wow/7 ratter and jitter characteristics, etc.

ものとなっている。For example, so-called film belts, typified by aromatic polyimide film belts, have good precision in belt finishing thickness and good wow/7 rattling and jitter properties, but they have poor antistatic properties and friction properties, and they also have poor tensile properties. The margin for assembly is small, and this causes considerable anxiety in terms of transmission characteristics, which may make it unusable. In addition, even if a flat belt is made of woven fabric as a core and coated or sheeted with rubber on the surface, the plain weave structure is unsuitable, so it is difficult to improve durability, tension characteristics, and wow.
7, the jitter characteristics are poor, and this is also unsuitable for practical use.
