PURPOSE:To obtain a high-speed, high-stability device by improving a resonance frequency of mechanical bending by improving the rigidity of a voice coil frame body constituting a voice coil, by providing crossing members to a voice coil main body. CONSTITUTION:A voice coil frame body 14 consists of the 1st frame body 15, 2nd frame body 16, four coupling members 17-20, the 1st crossing members 20 and 21, and the 2nd crossing members 23 and 24. Consequently, when the voice coil frame body 14 oscillates as shown by an arrow, mechanical bending caused by the oscillation at the low frequency of the voice coil frame body 14 is suppressed by the crossing members 23 and 24. As a result, the resonance frequency of the mechanical bending of the voice coil frame body 14 is improved, and consequently a high-speed, high-stability magnetic disk device is manufactured. |
