摘要： An optical disk apparatus according to the present invention includes: a controller 111, which receives an instruction that a layer-to-layer jump be performed from a current layer to a target layer; a layer-to-layer jump control section 146, which adjusts a spherical aberration correction value to the target layer and then gets the layer-to-layer jump attempted; a decision section 146 for determining whether the layer-to-layer jump has been carried out successfully; and a layer determining section 146 for determining, if the focus position has been set on a non-target storage layer as a result of the layer-to-layer jump, where the non-target storage layer is located in the optical disk. The layer-to-layer jump control section 146 shifts the focus position of the light beam from that non-target storage layer to the target layer by reference to information indicating which of the multiple storage layers the non-target storage layer is.

摘要： An optical disc apparatus according to the present invention includes a disc type recognizing section for determining whether the optical disc loaded is a first type, of which the number of information storage layers is less than a setting T (where T is an integer that is greater than two), or a second type, of which the number of information storage layers is equal to or greater than the setting T. Depending on whether the optical disc loaded has turned out to be the first type or the second type, the apparatus determines the read/write preprocessing (such as whether a fingerprint detection process needs to be performed or not).

摘要： An observation field of view of a microscope can be moved without moving or changing an objective lens and without varying position or state of a sample. A microscope optical system has a mirror that changes the direction of the optical path by reflection and is located in the optical path between an objective lens of the microscope and an image to be observed. The mirror is able to be tilted by changing the position of a reflecting surface of the mirror. Accordingly, the observation field of view is moved by tilting the mirror. In other words, the observation field of view can be moved without changing a positional relationship between the objective lens of the microscope and the sample.

摘要： Embodiments of the invention prevent contact between a peripheral edge of a magnetic disk and a counter surface of a ramp when the magnetic disk is displaced. In one embodiment, a ramp is disposed near the peripheral side surface of a magnetic disk. The ramp has magnetic disk retainers each having slide surfaces and counter surfaces respectively facing the recording surfaces of the magnetic disk. Grooves or recesses are formed in the counter surfaces to define relief spaces. When the peripheral side surface of the magnetic disk is displaced toward the counter surface by shocks exerted on the magnetic disk drive, the relief space prevents the peripheral edge from coming into contact with the counter surface. Thus the amount of particles produced by the collision of the magnetic disk with the ramp can be reduced.
摘要翻译：当磁盘移位时，本发明的实施例防止磁盘的周边边缘与斜面的对置表面之间的接触。在一个实施例中，斜面设置在磁盘的周边侧表面附近。斜坡具有各自具有分别面对磁盘的记录表面的滑动表面和相对表面的磁盘保持器。沟槽或凹槽形成在相对表面中以限定浮雕空间。当通过施加在磁盘驱动器上的冲击使磁盘的周边侧面朝向对置面移动时，释放空间防止周缘与对置面接触。因此，可以减少由磁盘与斜坡碰撞产生的颗粒的量。

摘要： The optical disk drive of the present invention can read data from multiple types of optical disks and includes: a motor for spinning a given optical disk; at least one light source for radiating light beams with multiple different wavelengths; at least one lens for converging each light beam onto the disk; a spherical aberration correcting section that can change the spherical aberration states of the beam; and a control section for controlling the operations of the motor, light source, lens and spherical aberration correcting section. The control section includes a disk type recognizing section that irradiates the disk with a light beam using the light source and the lens, thereby recognizing the type of the disk. The recognizing section performs the recognition by reference to first and second signal waveforms that have been generated based on the light beams reflected from the optical disk when the spherical aberration correcting section sets the spherical aberration states of the light beam to first and second states, respectively.

摘要： This optical disc drive can read and/or write data from/on an optical disc 20 with multiple information layers including first and second information layers. The drive includes: a light source 3, 4 that emits the light beam; an objective lens 1; an actuator 2 for moving the objective lens perpendicularly to the information layers; a focus error generator 7 for generating a focus error signal representing how much the light beam has been converged on a target one of the information layers; and focus control means for forming a focal point of the light beam on the target information layer by driving the actuator in accordance with the focus error signal. According to the present invention, while a focus jump is being made to shift the focal point of the light beam from the first information layer of the optical disc 20 to the second information layer thereof by moving the objective lens 1, wavelengths and/or numerical apertures for the light beam are changeable while the objective lens 1 is moving.

The drive includes: a driving mechanism 120, which is loaded with a selected one of the optical disks of the multiple types and which rotates the optical disk 102; an optical pickup 30 for irradiating the optical disk 102, which has been loaded into the driving mechanism 120, with a converged light beam, thereby generating an electrical signal based on light that has been reflected from the optical disk 102; and a control section (ODC 50) for controlling operations of the driving mechanism 120 and the optical pickup 30. The control section 50 includes a right/wrong side determining section for determining, by reference to the electrical signal generated by the optical pickup 30, whether or not the optical disk 102 has been loaded into the driving mechanism 120 with the other surface opposed to the optical pickup 30.
