摘要： A retract mechanism for a magnetic head which can read from and/or write to a disk, the mechanism includes a spring arm which supports the head and urges the head toward the disk. The spring arm includes a cam follower which rides along the surface of the cam, which has two parallel horizontal surfaces and two incline surfaces. The spring arm is moved by an actuator in a radial direction along the disk. When the spring arm is moved radially away from the center of the disk, the cam urges the spring arm upwardly, thereby lifting the head up and away from the disk. As the spring arm continues to move radially away from the center of the disk, the cam guides the spring arm such that the head rests safely on a landing platform.

摘要： A mechanism for a loading/unloading read and/or write head of a disk drive apparatus against a magnetic disk, includes a lifter which bends a suspension supporting the read and/or write head. The suspension is bent by moving a lifter up responsive to movement of the read and/or write head to detach the read and/or write head retained on a tip of the suspension from the magnetic disk by a given distance, thereby a high shock resistance is obtained.

摘要： 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.

摘要： In a diskette ejecting mechanism for magnetic disk unit being provided with a guide secured to a frame of the disk unit, an ejecting bedplate abutting against an end portion of a diskette and being mounted on the guide so as to be transferable in inserting and ejecting directions of the diskette, and a coiled spring energizing the ejection bedplate along the ejecting direction of the diskette. The mechanism does not require parts of suppressing the ejection bedplate such as conventional counter springs and the like because of utilization of torsional force of the coiled spring for ejecting the diskette as hooking force for the ejection bedplate.
