Facilitating the purchase and sale of private data between anonymous entities based on the use of encryption and a centralized on-line entity to exchange the private data in a secure environment. The seeker of private data, such as consumer information, transmits an encrypted query to the centralized exchange entity. The query submission includes legal representations stating the legally permissible purpose for seeking the information. The centralized exchange entity compares the encrypted query to an encrypted data index collected from at least one data provider, to determine if the query matches any private data held by a data provider. The comparison is conducted within a secure, search component to ensure the privacy of all data and all parties to the transaction. The exchange entity facilitates the anonymous exchange between the data purchaser and the data provider. A payment invoice can be generated and electronically presented by maintainer. The payment may be electronically debited from the designated account of a data purchaser and remitted to a data provider. In addition, a portion of such funds may be retained by the centralized exchange entity.

On an information recording medium, a data track pattern and a servo pattern composed of a concave / convex pattern including a plurality of convex parts are formed on at least one surface of a substrate and respective concave parts in the concave / convex pattern are filled with non-magnetic material. In the concave / convex pattern that constructs the servo pattern, a unit convex part length along a direction of rotation of the substrate and a unit concave part length along the direction of rotation are set so that the ratio of the unit convex part length to the unit concave part length decreases from an inner periphery to an outer periphery of the information recording medium.

On an information recording medium, a data track pattern and a servo pattern composed of a concave / convex pattern including a plurality of convex parts are formed on at least one surface side of a substrate and respective concave parts in the concave / convex pattern are filled with non-magnetic material. The concave / convex pattern that constructs the servo pattern is divided into a plurality of ring-shaped regions that are concentric with the data track pattern and has a unit convex part length along a direction of rotation of the substrate set in each ring-shaped region so that a value produced by dividing an average length of the unit convex part length in each ring-shaped region by a distance from a center of the data track pattern to the ring-shaped region decreases from ring-shaped regions in an inner periphery to ring-shaped regions in an outer periphery.

On an information recording medium, a data track pattern and a servo pattern composed of a concave / convex pattern including a plurality of convex parts are formed on at least one surface of a substrate and respective concave parts in the concave / convex pattern are filled with non-magnetic material. In the concave / convex pattern that constructs the data track pattern, the respective convex parts are formed concentrically or in a spiral. In the concave / convex pattern that constructs the servo pattern, a unit convex part length along a direction of rotation of the substrate is set so that a value produced by dividing the unit convex part length by a distance from a center of the data track pattern decreases from an inner periphery to an outer periphery.

In an information display panel, in which display media are sealed between a transparent front substrate and a rear substrate, and, in which the display media, to which an electrostatic field is applied from electrodes arranged respectively to the front substrate and the rear substrate, are made to move so as to display information such as an image, the rear substrate is constituted by a flexible material, and a metal electrode is formed on the rear substrate by a patterning process using a vapor deposition and a sputtering or a metal electrode is formed on the rear substrate by effecting a patterning process to a metal film formed by a vapor deposition or a sputtering. In this manner, it is possible to obtain an information display panel, which can improve a flexibility of the rear substrate with the electrode by an inexpensive cost, achieve an easy handling of the substrate and decrease a panel breakage due to a detachment of two substrates.

A pattern drawing apparatus which is capable of reducing manufacturing costs of information recording media. A partial drawing process is executed in response to output of a reference signal, for drawing, after being on standby for a predetermined standby time period, pattern segments, which are obtained by dividing patterns forming a servo pattern in the direction of the width of the patterns, by irradiation of a resin layer with an electron beam. A drawing position-changing process is executed for changing the irradiation position of the electron beam on the resin, toward a center of rotation of a substrate or away from the center of rotation, within a range of the effective drawing width of the electron beam. These processes are executed a plurality of times to draw an exposure pattern on the resin layer.

The invention provides a cluster resource control method used for a complicated production management system. The method comprises a process of enabling a client and a cluster system to interact based on a request unite task processing (RUTP-n) oriented adaptive load balance algorithm and a dynamic load balance algorithm, a process of performing registration and cancellation for a cluster resource coordinator by nodes and obtaining load and state information of the nodes in real time by the cluster resource coordinator, a process of detecting faulted nodes by the cluster resource coordinator and performing restarting and task transfer, and a process of electing a new cluster resource coordinator by other nodes to establish a new cluster system when the cluster resource coordinator has a fault. According to the method, a software load balance mode is adopted, dynamic distribution and adjustment can be performed according to resource conditions of the cluster nodes, and the faulted nodes can be processed in time, so that the overall throughput, efficiency and robustness of a service are effectively improved, the node number of a cluster server can be dynamically adjusted according to the demands, the utilization rate of the server is increased, and the costs of manufacturing enterprises in an informationization reform process are reduced.
