摘要： PROBLEM TO BE SOLVED: To prevent dropout of a head slider from a MEMS (micro electro mechanical system) and damage of the MEMS.
SOLUTION: In an embodiment, a suspension for slider DET has the MEMS 15 for holding the head slider. The MEMS has a clamper 51 for holding the head slider, and the head slider can be attached or detached by moving this clamper by external force. The suspension has limiters 56a, 56b for limiting the movement of the clamper in a lateral direction. The limiter limits the undesirable movement of the clamper, which prevents movement of the clamper in the lateral direction when attaching the head slider, dropout of the head slider and the damage of MEMS caused by contact with a magnetic disk, or dropout of the head slider and the damage of MEMS in handling.

摘要： PROBLEM TO BE SOLVED: To effectively suppress vibration of a disk in a hard disk drive (HDD) with low density gas sealed therein, and surely prevent leakage of the low density gas from the base. SOLUTION: In an embodiment, helium gas is sealed in a hermetically sealed enclosure of an HDD, and a shroud 21 is integrally formed with a base 102. In manufacturing the base, a surface 211 of the shroud facing a magnetic disc is shaped by cutting after die-casting. This accomplishes a small and precise size of the gap between the surface of the shroud facing the magnetic disk and the circumferential edge of the disk. Cutting the shroud formed independently from the exterior walls 23a-23d, which ensure the hermetic property with the shroud, suppresses the vibration of the magnetic disk and eliminates the necessity of cutting of the inner surfaces 232a-232d of the exterior walls for the purpose of suppression of the vibration to reduce the risk of helium leakage.

摘要： PROBLEM TO BE SOLVED: To surely lock an actuator rotated due to shocks from the outside.
SOLUTION: A latch 18 and an actuator 14 have a structure in which the latch 18 can latch the actuator 14 at two different swing angles. The swing angle of the latch 18 is an angle in rotation centered on a rotational shaft 181 (rotation angle). The latch 18 may be engaged with the actuator 14 at a shallow angle in Fig.4(a), or the latch 18 may be engaged with the actuator 14 at a deeper angle in Fig.4(b). Since the latch 18 is able to latch the actuator 14 at different swing angles, the actuator can be securely latched.

摘要： PROBLEM TO BE SOLVED: To suppress occurrence of charged foreign matter having a particle size of less than 1 μm in a method for forming a magnetic disk carbon protective film using cathodic arc discharge with a magnetic field filter. SOLUTION: Plasma is generated by the arc discharge of cathode 13 using carbon as a main component. The generated plasma is held by a first magnetic field duct 17 and transported by a second magnetic field duct 18 to a processing chamber 27. A carbon protective film is formed on a magnetic disk substrate 23 arranged in the processing chamber. Then, the direction of the magnetic flux density 17 generated by the second magnetic field duct 18 is set in the opposite direction to the direction of the magnetic flux density 16 generated by the first magnetic field duct 17. The magnetic flux density generated by the first magnetic field duct 17 and the second magnetic field duct 18 is controlled so that a zero magnetic flux plane 12 produced between the first magnetic field duct and the second magnetic field duct is spatially in agreement with the outermost surface 11 of the cathode.
