    摘要: This invention relates to a magnetic head device and a disk drive, which are suitable for application to a mass-storage floppy disk drive. A first and second rails are provided on the disk side in projected form on a slider of each of magnetic head elements 20 so as to extend in a tangential direction R of a track of the disk and be parallel with each other. A head chip for recording and reproducing data in a state of being in contact with a recording surface of the disk and in a standard recording density is provided substantially in the central position of the first rail. Another head chip for recording and reproducing data in a state of being levitated from the recording surface of the disk and in a high recording density is provided in a position on the rear side of the second rail 26b with respect to the tangential direction R of the track. A width of the first rail of each magnetic head element is narrower than a width of the second rail thereof. The slider is inclined and levitated so that the second rail approaches the recording surface of the disk.

    摘要: To provide a magnetic powder production method, a magnetic sheet production method, and an antenna module production method that are capable of reducing a size of magnetic particles, achieving thinning and a low loss, and improving magnetic permeability without lowering it.At least two oxide-based magnetic materials are mixed, preliminarily calcined, and pulverized. The pulverized magnetic materials are typically formed into a paste by being dispersed in an organic solvent, and the magnetic materials are applied onto a film after being subjected to defoaming processing. Accordingly, a sheet-like magnetic material is formed. The sheet-like magnetic material is cut into predetermined sizes so as to be fragmented into particles, with the result that magnetic particles are formed.

    摘要: A magnetic core member, an antenna module, and a portable communication terminal having this, which have a configuration capable of satisfying enhancement of communication characteristics of antenna coils as well as their sufficient electromagnetic shielding function from a shield plate. A magnetic core member (4) is disposed between an antenna substrate having antenna coils (11), (12) formed therein and a conductive shield plate (3), and is formed by filling an insulating material (30) with a magnetic powder (31). The magnetic core member (4) has a two-layered structure including a first layer (4A) and a second layer (4B), thereby making a filling rate of the magnetic powder (31) in the first layer (4A) be lower than that of the magnetic powder (31) in the second layer (4B) so that a first surface (4a) on a side opposed to the antenna substrate (2) and a second surface (4b) on a side opposed to the shield plate (3) have magnetic properties different from each other.

    摘要: This invention provides an antenna apparatus (60) for use in a non-contact type IC card into and from which data can be written and read by electronic apparatuses having a communication function, by virtue of inductive coupling. The antenna apparatus comprises a loop coil (61) and a magnetic member (62). The loop coil is produced by winding a conductive wire in a plane and configured to perform the inductive coupling. The magnetic member covers one region (61a) of the loop coil, provided at one side, from one surface of the loop coil, passes through the loop coil, and covers the other region (61b) of the loop coil, provided at the other side, from the other surface of the loop coil. The entire region of the loop coil is thus covered.
