摘要： An integrated retrieval scheme retrieves data involved in a plurality of semi-structured documents scattering over open networks and collects the required information item by item from the semi-structured documents through a unified interface without regard to differences in the document structures, presentation styles, and elements of the semi-structured documents. The search scheme receives a query consisting of search items and search conditions from a user. The search scheme finds, according to location data that specifies the location of each of the semi-structured documents, the location of each semi-structured document that contains all search items and converts, if necessary, item presentation styles of the entered query into that of the location found semi-structured documents according to style conversion data, and forms queries for the location found semi-structured documents, and transmits the queries to the found locations and obtains the location found semi-structured documents, and extracts item data from the obtained semi-structured documents according to structure data being used to delimit document into items and attribute data being used for conditional retrieval, and prepares a search result, and converts, if necessary, item presentation styles of the search result into the item presentation styles of each user according to the style conversion data.

摘要： An information recording and reproducing method and apparatus with increased recording density of an information recording medium using the sample servo method driven with a fixed angular velocity from the innermost circumference to the outmost circumference. A disk-shaped recording medium is concentrically divided into a plurality of areas. Recording is performed with a recording density suited for the radial position of each of the areas. The width of the areas is set so that the recording capacity of a user data section sandwiched between servo sections forming a segment may increase with every transition to an outer adjacent area while taking one byte as a unit. The recording and reproducing apparatus has a clock generating circuit for servo data extraction and a clock generating circuit for user data extraction. The latter clock generating circuit is synchronized by a synchronizing pulse generated by the former clock generating circuit.
