摘要： Disclosed is a magnetic disk apparatus having a large internal accommodation space. This magnetic disk apparatus comprises a case defining accommodation space inside, magnetic disks disposed in the accommodation space, a spindle motor, magnetic heads and a rotary actuator. The case includes a cover having a first flat portion and a first upright portion standing upright on the first flat portion at a peripheral portion thereof, and a base having a second flat portion and a second upright portion standing upright on the second flat portion at a peripheral portion thereof. This design can ensure a sufficient strength even if the case is made thin, thus allowing the internal accommodation space to be increased. The magnetic disk apparatus also has a printed circuit board, which is provided at the case and has a control circuit mounted thereon for controlling the magnetic heads. The printed circuit board supplies a source voltage to the case. Accordingly, the magnetic disks and the magnetic heads can be kept at the same potential via the case.

摘要： A protection film is layered over the trailing or outflow end surface of a slider body in a head slider for a recording medium drive. A head element is embedded within the protection film. The head element generates heat in response to the supply of an electric current. The heat causes thermal expansion of the protection film. The tip end of the head element thus excessively approaches the recording disk beyond the medium-opposed surface of the head slider. The flying height of a protection protuberance is set smaller than a flying height of the head element even when the protection film suffers from thermal expansion. The protection protuberance is allowed to trace an orbit closer to the recording medium than the orbit of the head element. The protection protuberance is allowed to collide against obstacles on the recording medium in front of the head element.

摘要： A flying head slider comprises a flying surface opposed to the surface of the magnetic disk. Inner and outer rails are formed on the flying surface. Air bearing surfaces (ABS) are defined on the inner and outer rails. A magnetic head element is embedded in the outer rail at the protection layer attached to the end surface of the slider body. A splay is formed on the air bearing surface (ABS) of the outer rail. When the head slider takes off from the surface of the magnetic disk, the head slider takes a slant attitude with the protection layer nearest to the surface of the magnetic disk. The splay in the outer rail serves to avoid the protection layer from colliding with the surface of the magnetic disk even when the head slider rolls. The head slider is capable of making the magnetic head element thereon approach the surface of the magnetic disk as much as possible even if the head slider is expected to change its attitude.

摘要： A storage device includes a controller and a circuit. The controller controls a flying height of a slider from a recording medium as a result of applying voltage between the recording medium and the slider. The slider has a reading element for reproducing information recorded on the recording medium. The circuit makes an electric potential of a reference voltage of a driving circuit and the reading element and an electric potential of the recording medium equal to each other. The driving circuit drives the reading element.

摘要： A protector protuberance is formed on a head slider incorporated in a recording medium drive such as a hard disk drive. The protector protuberance is allowed to collide against a contamination on a recording medium in front of a head element mounted on the head slider. The head element can be protected from collision against the contamination behind the protector protuberance. The protector protuberance is located as close to the head element as possible. Even with a smaller protector protuberance, the front and rear support protrusions contact the recording medium so as to hold the slider body above the surface of the recording medium. An increase can be prevented in the adsorption acting between the slider body and a lubricant agent spreading over the surface of the recording medium. A smaller protector protuberance enables the head element to approach the recording medium as close as possible upon read/write operations.
