Embodiment Construction

[0034] The resin part (resin molded body) of the present invention is (1) an insulating sleeve, (2) a carriage, or (3) a slideway used inside a recording disk drive device. The recording disk drive device using the resin part of the present invention has passed figure 1 Be explained. figure 1 It is a perspective view with the top cover of the recording disk drive unit removed. The recording magnetic disk drive device 1 rotates the magnetic disk 7 fixed to the motor 2 in the resin case 6, and at the same time reads information from the magnetic disk 7 and transfers information to the magnetic disk 7 by the reading head 3a provided at the front end of the swing arm 3. The disk device to write to. In addition, the carriage 4 integrally formed with the coil 4a for swinging the swing arm 3 around the shaft 3b is provided to maintain weight balance with the swing arm 3 . Furthermore, a slideway 5 for retracting the head 3 a when the magnetic disk 7 is stopped is provided in the r...

Abstract

Provided are a resin component used inside a recording disk drive device, having superior fire retardancy while the generation of outgas is reduced, and a recording disk drive device using the resin component, having high reliability. A resin component used inside a recording disk drive device (1) comprises an insulating bushing for protecting a lead wire from a motor (2) when the lead wire is connected to a circuit board, a carriage (4) for having a weight balanced structure with a swing arm (3) which is integrally formed with a coil for driving the swing arm (3) having a pickup head (3a) provided at the tip thereof in order to read information from and write information to a recording disk (7), or a ramp (5) for receiving the pickup head (3a) while the recording disk is stopped. The resin component is a resin compact of an amorphous resin, a crystalline resin, or a liquid crystal resin, and the outgas generated from the resin compact is no more than 30 ppm when measured by a prescribed method.

Description

technical field [0001] The present invention relates to a recording disk drive device, and more particularly, to a resin component used inside the recording disk drive device. Background technique [0002] Recording disk drive devices such as hard disk drives are required to be free of dust in the interior as the storage density becomes higher, and there is an increasing demand for very strict cleanliness without outgassing or ion contamination from the materials of each component. . In addition, there is a flame-retardant standard "UL94V0" as a characteristic required for internal parts, and in order to satisfy this characteristic, polybutylene terephthalate (PBT) materials mixed with phosphorus-based flame retardants have been used conventionally. . However, there is a problem of occurrence of outgassing caused by this flame retardant. [0003] It is known that the casing of the recording disk drive device is made of at least one of carbon fiber and inorganic fiber as a...
