Title: Focusing servo device
Inventor: KAWANO AKIRA
IPC: G11B7/095
Filed: 1989-11-22
Abstract: PURPOSE:To make address crosstalk distortion sufficiently small by setting a correcting voltage properly, then performing control to the best focusing state in reproducing operation for either of a data area and an address area, and obtaining an excellent data error rate. CONSTITUTION:An offset adding circuit 17 and an offset switching circuit 18 are added to a conventional device. When the ADDG signal from an external control system which is not shown in a figure indicates address area reproducing operation, a switching circuit 18 generates a correcting voltage for canceling the offset quantity at the focusing point of a focusing error signal, but when data area reproducing operation is indicated, a corresponding correcting voltage is generated and supplied to an offset adding circuit 17. The adding circuit 17 adds the correcting voltage to the focusing error signal FE4 to generate and supply a focusing error signal FE5 whose offset is canceled to a driving circuit 11, thereby driving a coil 12. Thus, the error rate of data is held excellently and the address crosstalk distortion can be reduced sufficiently.

Abstract: PURPOSE:To select optimal information with the use of the information concerning a target character by preparing a dictionary which provides plural indexes and an other-part referring index, and selecting one of plural search keys on a multi-window screen with a user. CONSTITUTION:Three types of the retrieve of 'how two read,' 'the number of strokes' and 'radical' for retrieving keys in a retrieving means 7. In a similar character retrieving means 8, the character other than that, which completely corresponds, can be retrieved concerning the respective keys. For example, when 'the number of strokes' key is used, a range in which one, two or three is added or subtracted to or from the stroke number can be retrieved. When the character is retrieved by the 'radical,' it can be retrieved even if the radical is not the basic part. Further, it can be retrieved based on the similar character structure part or the radical in the same number of strokes. It can be retrieved by the number of the strokes of the residual part of KANJI (Chiness syllabary) out of KANJI including the radical. Further, at the time of the retrieve from 'how to read,' KANJI in the similar reading in pronunciation can be retrieved.
