Magnetic disk drive with carriage having bobbin supporting annular coil connected by connection members |
摘要 |
A magnetic disk drive comprises at least one magnetic head for reading and writing information on at least one magnetic disk, a carriage supporting the magnetic head over the magnetic disk for movement of the magnetic head about a predetermined shaft, an annular coil supported by a bobbin provided on the carriage and subjected to an electromagnetic force for driving the carriage. The drive further comprises a first connection member for joining the annular coil and the bobbin, an in-coil member arranged inside the annular coil, and a second connection member for joining the in-coil member and the annular coil. A modulus of longitudinal elasticity of the in-coil member is larger than that of the first or second connection member. The drive thus formed has the increased carriage rigidity, the improved positioning accuracy of a magnetic head and the increased recording capacity of the disk.
