Abstract: A display apparatus according to an embodiment of the present technology includes at least one display module (9). The at least one display module includes a display panel (12), a support base (51), and an adjustment mechanism (52). The display panel is capable of displaying an image. The support base supports the display panel. The adjustment mechanism is connected to the display panel and connected to the support base, the adjustment mechanism being capable of adjusting a relative distance of the display panel to the support base. This makes it possible to display a high-quality image.

Abstract: A head actuator is made thinner without sacrificing its strength to thereby achieve the thinning of a hard disk apparatus. On the base end of each of two suspensions is provided a boss that protrudes in the direction of the side on which a magnetic head is provided, and a suspension fixing section having a hole into which the bosses are inserted is formed towards the tip of an arm. The boss of one of the suspensions is inserted into the hole from the upper end section thereof, and the boss of the other suspension is inserted into the hole from the lower end section thereof. Thus, the arm is fixed in place by being held by the two suspensions from above and below.

Abstract: A rotor is provided which is rotatably disposed between a first shell and a recording medium, in a containing space formed inside the first shell and a second shell. The rotor includes a first wall formed along the circumferential direction of the rotor, and a part of the first wall is cut out to form a first opening. The second shell includes a second wall formed so as to overlap with the inside of the first wall along the outer circumference of the recording medium, on the outside in the radial direction of the outer circumference of the recording medium. The second wall and the first wall constitute a labyrinth structure portion for isolating the recording medium and the exterior of the recording medium from each other. With the rotor rotated, the first opening and a second opening constitute a head in/out opening.
