摘要： An optical pickup is provided below an optical disk. A laser beam is emitted from a semiconductor laser onto a track, through an objective lens. The objective lens is capable of shifting, and is shifted in the direction of the track width by a magnetic force from a tracking actuator, thereby performing lens tracking. The optical pickup is mounted on a carriage. The carriage is shifted along the radial direction of the optical disk by a voice coil motor. This shifts the laser beam along the radial direction of the optical disk, thereby performing track access. Upon reception of an access command, a velocity control mode commences, and the shift velocity of the carriage is controlled in accordance with a velocity control signal corresponding to the distance between a target track and a current track. When the pickup arrives near the target track, the generation of velocity control signal ceases and the location control mode commences. When the carriage is deviated from the target track, its servo is adjusted in accordance with its deviation, by a location control signal. During velocity control of the carriage, a lens damping signal corresponding to the velocity control signal is supplied to the objective lens. After location control of the carriage commences, the lens damping signal corresponding to a location cotnrol signal is supplied to the objective lens until the velocity of the carriage falls below a predetermined value.
摘要翻译：在光盘下面设置光拾取器。激光束通过物镜从半导体激光器发射到轨道上。物镜能够移动，并且通过来自跟踪致动器的磁力在轨道宽度的方向上移动，从而进行透镜跟踪。光学拾取器安装在滑架上。滑架通过音圈马达沿着光盘的径向方向移动。这样沿着光盘的径向移动激光束，从而进行轨道通路。在接收到访问命令时，开始速度控制模式，并且根据对应于目标轨道和当前轨道之间的距离的速度控制信号来控制滑架的移动速度。当拾音器到达目标轨道附近时，速度控制信号的产生停止，位置控制模式开始。当滑架偏离目标轨道时，其伺服根据其偏差根据位置控制信号进行调节。在滑架的速度控制期间，将对应于速度控制信号的透镜阻尼信号提供给物镜。在开始滑架的定位控制之后，将对应于位置辅助信号的镜头阻尼信号提供给物镜，直到滑架的速度降到预定值以下。

摘要： An optical pickup is arranged under an optical disk. Tracks of the disk are irradiated with a laser beam from the pickup. A beam reflected by a given track becomes incident on the pickup. A tracking error signal from the pickup is supplied to a lens moving actuator through a gain phase compensating circuit and a lens driving circuit, and an objective lens in the pickup is radially moved along disk. The tracking error signal is supplied to a voice coil motor through the phase compensating circuit. A carriage carrying the pickup thereon can be radially moved along the disk. When a tracking instruction is generated, the lens driving circuit drives the objective lens to start tracking. Meanwhile, the low-frequency components of the tracking error signal which are lower than the resonance frequency of the lens tracking circuit are amplified by the gain phase compensating circuit. When the tracking error signal is converged within a predetermined threshold range, the amplification of the low-frequency components of the tracking error signal is stopped. At the same time, the operation of the voice coil motor is started. Tracking is performed by both the objective lens and the carriage to achieve two-step servo tracking.

摘要： A vibration detection system comprises a battery-less vibration sensor and an interrogator. The sensor comprises a single port surface acoustic wave resonator. The interrogator continuously transmits a carrier wave signal to the resonator while receiving a wave signal reflected from the resonator. The reflected wave signal includes components other than the transmitted carrier wave signal if the sensor senses a vibration event. Based the reflected wave signal, the interrogator judges whether the vibration event occurs.
