  • Laser power calibration method for an optical disk apparatus
    Publication number: 20050083802
    Abstract: Laser light irradiation can be performed on a recordable surface in a defocused state with a high-power laser beam with safety without incurring data destruction due to erroneous data recording or overwrite recording even in the recording on an eccentric disk or regardless of occurrence of wobbling of the disk surface. Laser irradiation is performed after moving an objective lens radially inwardly beyond a PCA located at an inner peripheral portion of the disk (or radially outwardly beyond the PCA located at an outer peripheral portion of the disk) by using a tracking coil.

  • Vehicle-mounted information processing apparatus having magnetic disk device
    Patent number: 6862505
    Abstract: A vehicle-mounted information processing apparatus such as a car-navigation system detects that a key switch of the vehicle has been set up at a Lock position (i.e., the engine is stopped). After that, the apparatus performs data reproduction of data files in an order from the oldest, then re-recording the reproduced data files with no change added thereto. Here, the above-described data files, which are stored within a magnetic disk device built in the apparatus, have been not updated for a constant time-period. This re-recording prevents a data loss caused by a thermal decay in the case where the magnetic disk device is mounted inside the vehicle that is likely to have existed under a high-temperature environment for a long time-period.

  • Method of mounting electronic component, structure for mounting electronic component, electronic component module, and electronic apparatus
    Publication number: 20040238603
    Abstract: The invention provides a method of mounting an electronic component where an electronic component can be reliably electrically-connected to a substrate. A substrate defines a through-hole that extends through the substrate, from connection electrodes formed on the lower surface of the substrate, to the upper surface of the substrate. A low melting point metal is connected to the connection electrodes and fills the through-hole. A bump and the low melting point metal are alloyed and bonded by heating the low melting point metal while pressing the bump formed on an electrode pad of an electronic component, with respect to a front end of the low melting point metal. The active surface of the electronic component is sealed by the upper surface of the substrate.

  • Anisotropically conductive adhesive, mounting method, electro-optical device module, and electronic device
    Publication number: 20040234763
    Abstract: This invention provides a mounting method for reliably connecting mounting components electrically. Specifically, an anisotropically conductive adhesive can be composed of crushable microcapsules and a second liquid in which the microcapsules are dispersed. Each microcapsule encloses a first liquid and a conductive particle. The first liquid can react with the second liquid at normal temperatures to cure the second liquid. This anisotropically conductive adhesive can be applied on a flexible printed circuit (FPC). Then, a drive IC is mounted and pressed on the FPC to crush the microcapsules between electrode pads provided on the drive IC and electrode pads provided on the FPC, thereby bonding the electrode pads. Subsequently, the anisotropically conductive adhesive is heated to plasticize a capsule wall of each microcapsule, thereby bonding the drive IC and the FPC.
