摘要： The present invention provides an optical head for realizing the stable operation by controlling the temperature of the semiconductor laser to a low level by reducing the heat transfer rate from a laser driver IC to a housing in the vicinity of a semiconductor laser, and an optical disc drive using the same. It provides an optical head having a semiconductor laser and a photo detector arranged on one side with respect to a straight line through the center of an object lens of an object lens actuator and in parallel to the axis contacted with bearings, and a laser driver IC arranged on the other side with respect to the straight line. Thereby, the distance from the laser driver IC to the semiconductor laser can sufficiently be ensured so that the heat transfer rate from the laser driver IC to the housing can be reduced.

摘要： In a background-art optical disk drive, it is necessary to improve acceleration generated in an objective lens driving device in order to make an objective lens track a disk rotating at a high speed. This can be achieved either by increasing a thrust force acting on a movable body including the objective lens or by making the movable body lighter in weight. One method for increasing the thrust force is to make permanent magnets larger or use permanent magnets having a large magnetic force. However, this leads to such a problem that the unit becomes larger in size or higher in cost. In order to solve the foregoing problem, an inner yoke is disposed around a beam of light and inside the movable body of the objective lens driving device. Alternatively, an inner yoke having at least two sides substantially parallel with the radial direction of the disk and at least two sides substantially perpendicular thereto is disposed inside the movable body.

摘要： When an update disable signal is at an inactivation level, a latch signal is activated in accordance with an active signal and a mode register set signal. When the update disable signal is at an activation level, the latch signal is activated in accordance with the active signal while being not activated in accordance with the mode register set signal. Based on the latch signal, the address signal is latched. Based on the latched address signal, an internal test signal is generated. With this structure, a target chip can be selectively controlled simply by activating the update disable signal in the target chip.

摘要： In a command generating circuit, operation mode signals (signals determining internal operations, such as ACTIVE, READ, WRITE, and PRECHARGE) are determined by decoding command signals /CS, /RAS, /CAS, and /WE. The operation mode signals and bank select signals (BS0, BS1, BS2, and BS3) are latched by internal clocks. Thereafter, a logical product (AND) of each of the latched operation mode signals and each of the latched bank select signals is calculated.
