Title: Magnetic recording and reproducing device
Inventor: UEHARA TSUKASA
IPC: G11B17/043
Filed: 1988-06-09
Abstract: PURPOSE:To prevent an electrostatic plunge into a head and to smoothen the rotation of a disk by constituting a holder for a magnetic recording medium of electrically conductive plastics. CONSTITUTION:The holder 9 for receiving a cassette 2 is constituted of the electrically conductive plastics. When the magnetic disk 1 is rotated by a disk rotating motor 31, static electricity is generated by the friction with the recording and reproducing head 34 or a stabilizer plate 20, thus charging the disk 1. This static electricity is collected by a liner 6, etc., to be led to the cassette 2. Since the cassette 2 is generally constituted of electrically conductive plastics, the static electricity is conducted through the cassette 2 to the holder 9, and most of it runs away. In addition, a part of it runs away from an engaging part of a positioning pin provided on a chassis substrate 36 with a positioning hole of the cassette 2. Thus, since the electric charge is not collected to the disk 1 and the cassette 2, the electrostatic plunge into the head 34 is hence prevented.

IPC: G11B19/20
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To decrease the rotation asynchronous vibration quantity of a spindle by adding a specified radial prepressure on the spindle shaft on its central extension line toward its outer periphery in a manner as not to deform the outer rings of spindle bearings of a high-speed rotating spindle structure. SOLUTION: Pins 7 are fixed in parallel with the shaft 3 to the outer rings of the spindle bearings 4-1, 4-2. The pins 7 are similarly fixed to a cover 5 facing the spindle bearings 4-1, 4-2 and a housing 15 as well. The straight lines connecting the respective pins 7 are so arranged as to pass the center of rotation of the spindle bearings 4-1, 4-2. Coil springs 6 are mounted at the respective pins 7, by which the force in the outer peripheral direction relative to the bearing centers is acted on the spindle bearings and the spindle bearings are positioned and fixed to the radial direction. Since the working point of the pressing force in the radial direction to be exerted on the outer rings of the spindle bearings is set at the position nearer the outer periphery than a trajectory radius, the deformation quantity of the outer rings may be decreased.
