    摘要: The present invention is aimed at providing an optical disk, an optical disk device, and an optical disk reproduction method, for allowing for stable and efficient reading of address information. The optical disk includes a plurality of tracks each divided into a plurality of recording sectors. Each of the recording sectors includes a header region. The header region includes address information for identifying the position of the corresponding recording sector and address synchronous information for identifying the recording position of the address information for bit synchronization. The address information has been modulated using a run length limit code of a maximum inversion interval of Tmax bits (Tmax is a natural number), and the address synchronous information includes two patterns of which inversion interval is (Tmax+3) bits or more, so that the reproduced signal of the address synchronous information is distinguished from the reproduced signal of other information.

    摘要: A method for controlling the rotational speed of a disk player includes first calculating the proportion of time which the disk player is reading data from the disk during a unit time T. Thereafter, the method increases the rotational speed of the disk player if the proportion of time that the disk player spends reading data from the disk is greater than a first threshold during each of m consecutive units of time T, and decreases the rotational speed of the disk player if the proportion of time that the disk player spends reading data from the disk is less than a second threshold during each of n consecutive units of time T.

    摘要: Ferroelectric thin films can hold non-volatile memories with bit sizes down to 30 nm at room temperature. This invention provides a data storage system that preferably comprises an electrically conducting rotatable hard disk substrate having a ferroelectric storage layer that comprises storage cells which can be written and read along concentric recording tracks, a pivoted servo arm with a free end for movement across the recording tracks. The free end of the servo arm includes both a write head, consisting of an electrically conducting tip, and a read head, consisting of a field effect transistor (FET), held close to the disk surface. The FET has a gate electrode and is positioned on the servo arm with the gate electrode held close to the ferroelectric surface of the disk during read operations of the data storage system. Read and write operations can be performed with standard semiconductor technologies in combination with existing magnetic hard-disk servo-control architecture. Such ferroelectric hard disk data storage systems are expected to increase the areal storage density of hard disks beyond the superparamagnetic limit of around 40 GB/in2.

    摘要: To obtain good approximate solutions of a combinatorial optimization problem such as traveling salesman problem and to enable its processing apparatus in form of massively parallel exclusive devices, an information carrier corresponding to the distribution of a plurality of points given on an n-dimensional space (n is an integer not smaller than 2), and time development and time reversal of the information carrier are used to process the information. The information carrier may be the density of particles or optical intensity corresponding to the distribution of the given points, and a diffusion process of the particles or a defocusing process is used as changes with time. The traveling salesman problem is solved by using this method.

    摘要: A positioning mechanism for positioning in a direction of movement. The positioning mechanism comprises a first member and a second member movably mounted relative to one another, and additionally comprises an elongate bending element disposed between the first member and the second member, perpendicular to the direction of movement. The elongate bending element includes two end portions attached to the second member. A portion of the elongate bending element other than the end portions is coupled to the first member. The elongate bending element bends lengthways in response to an applied driving signal to move the first member relative to the second member in the direction of movement.

    摘要: Data storage media are integrated into a microfabricated data storage system. Each data storage medium is located on one surface of a movable support. Flexures connected to the movable support allow the medium to move within a plane so that data can be stored at different locations on the medium, but significantly resist any out of the plane motion of the medium. Therefore, tips or other devices for writing or reading to or from the medium can be placed a small distance from the medium, thereby facilitating microfabrication of the data storage system. First electrodes are coupled to a second surface of the movable support opposite the medium. Second electrodes are located opposite the first electrodes to form an electrostatic surface actuator. Electric fields generated by the second electrodes interact with an electric field generated by the first electrodes to apply a force to the first electrodes and, hence, the movable support and the medium. After forming the media on a microfabricated wafer, the wafer can be bonded to another microfabricated wafer, and the resulting structure can thereby be sealed by a gasket to seal the media within the data storage system. Preferably the bonding process to join the microfabricated wafers is CMOS (complementary metal-oxide semiconductor) compatible by using elements such as palladium and silicon that bond at relatively low temperatures.
