ABSTRACT:
A magnetic disk drive. A cartridge for accommodating a magnetic recording medium also accommodates an actuator and a spindle. The spindle accommodated in the cartridge is driven by a spindle driving mechanism provided in a driving device so as to rotate the magnetic recording medium. The actuator is driven by an actuator driving mechanism provided in the driving device so as to move a magnetic head approximately in the radial direction of the magnetic recording medium. The cartridge includes a shutter mechanism which is opened so as to expose at least a part of the spindle and the actuator in such a manner as to face the actuator driving mechanism and the spindle driving mechanism, respectively, when the cartridge is mounted on the driving device and which is closed so as to enclose the spindle and the magnetic head and the actuator in the cartridge in a sealed state when the cartridge is removed from the driving device. The cartridge further includes a ramp loading mechanism for protecting the magnetic head from an external shock when the cartridge is removed from the driving device.
