摘要： A state detection circuit comprises: a first counter circuit that counts a series of first command signals indicative of start of an operation control; a second counter circuit that counts a series of second command signals indicative of completion of the operation control; a count coincidence detection circuit that detects coincidence between a count in the first counter circuit and a count in the second counter circuit; and a state storing circuit that is set by the series of first command signals and reset when coincidence is detected by the count coincidence detection circuit. The first and second counter circuits each comprise a binary counter.

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： 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.
