Abstract: A lamp connector comprises a contact and a connector body having an accommodation space accommodating the contact. The contact has a positioning hole. The connector body has a slot extending along an insertion direction of the contact and confining the contact thereinside. The accommodation space has a elastic member with a barb that corresponds to the positioning hole and has a guide slope. The contact can easily overcome elastic force of the elastic member, overpass the guide slope to go into the accommodation space and is longitudinally confined to the slot. Then, elastic force springs the barb into the positioning hole. Thus, the contact is transversely positioned in the plastic body. Thereby, the contact can be assembled to the plastic body faster, more conveniently and more firmly; the electric connection of the male plug and the female socket is more stable and more resistant to electromagnetic interference.

In some examples, the raised portion is to further facilitate establishing the electrical contact upon removal of the electrical module from the cavity.

Abstract: A system and method for measuring the modulation between a magnetic head and a magnetic storage medium, such as a disk, is disclosed. A magnetic read/write head is positioned above a magnetic storage medium at a given flying height. The magnetic read/write head reads a signal from the magnetic storage medium. A tester measures an alternating electric current between the magnetic read/write head through the slider and the magnetic storage medium. A computer may then calculate the modulation by the magnetic read/write head based on the alternating electric current. A DC voltage to the head may be applied to lower the flying height of the magnetic head.

Abstract: A slider is formed by a three-step ion milling process with an ABS topography that provides aerodynamic stability at sub-nanometer flying heights. The ABS design significantly eliminates the accumulation of lubricant and removes whatever lubricant does accumulate by use of a shallow dam at the trailing edge. In addition, a junction between a down-track channel and a cross-track channel directs airflow towards a center pad in which a transducer is embedded so that the pressure at the pad is enhanced even under high altitude conditions. The slider ABS is divided into two portions by a transverse deep air channel, but the channel is bridged by the cross-track channel which crosses the deep air channel with sides of unequal height. This dual height bridge allows variations in skew angle to be compensated so that pressure variations across the disk tracks are significantly reduced.

Abstract: A magnetic disk is protected by a bilayer. The bilayer is formed as an adhesion enhancing underlayer and a protective diamond-like carbon (DLC) overlayer. The underlayer is formed of an aluminum or alloyed aluminum oxynitride, having the general formula AlOxNy or MezAlOxNy where Mez symbolizes Tiz, Siz or Crz and where x, y and z can be varied within the formation process. By adjusting the values of x and y the adhesion underlayer contributes to such qualities of the protective bilayer as stress compensation, chemical and mechanical stability and low electrical conductivity. Various methods of forming the underlayer are provided, including reactive ion sputtering, plasma assisted chemical vapor deposition, pulsed laser deposition and plasma immersion ion implantation.

Abstract: A protective bilayer on a magnetic read/write head or magnetic disk is formed as an adhesion enhancing and corrosion resistant underlayer and a protective diamond-like carbon (DLC) overlayer. The underlayer is a transition metal oxynitride, having the general formula MeOxNy, where Me represents a single element or an alloy of the following transition metal elements: Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, and W, here x can be within the range between 0 and 3 and y is in the range between approximately 0 and 2. Adjusting the values of x and y contributes to such qualities of the protective bilayer as stress compensation, chemical and mechanical stability and low electrical conductivity.

Abstract: A method and apparatus for improving flying height stability in a small form factor hard disk drive that typically moves at lower speeds is achieved by a slider having an ABS with an air channel and pocket. The air channel and pocket are configured to increase the amount of aerodynamic lift provided by normally smaller amounts of intake air at the inner diameter of the rotating disk and, thereby, to achieve a desired flying height profile.

Abstract: A DFH (Dynamic Flying Height) type slider ABS design has a stable flying height and a DFH efficiency that is uniform across the entire disk surface. These properties are a result of embedding the read/write head and heater in a trapezoidally bridged micro-pad having a very small surface area. The micro-pad is surrounded by a wing-like structure that projects from a central rail in the ABS and the micro pad is connected to an inner edge of that structure by a bridge having a trapezoidal shape. The trapezoidal shape responds effectively to variations in air flow direction and pressure point as the slider moves across the disk surface and, as a result, provides the uniform DFH efficiency. At the same time, the projecting wings and adjacent topology help to direct the airflow around the micro-pad and provide the stable flying height.

Abstract: A slider is formed with an ABS topography that eliminates the accumulation of lubricant swept from the surface of a rotating disk in an operating HDD. The topography includes air channeling grooves in which are formed backflow blocking elements that prevent the formation airflow patterns that would cause lubricant to be aspirated into the ABS topography of the slider and that create airflow patterns that sweep lubricant away from the ABS of the slider. The topography is first tested to make sure that the slider has the proper flying height and aerodynamic stability, then the backflow blocking elements are added to control the airflow, while maintaining the desired flying height and stability.
