Title: Recording and reproducing device
Inventor: TAKAUCHI KENJI
IPC: G11B27/10
Filed: 1988-12-01
Abstract: PURPOSE:To prevent a retrieval error with minimum constitution by retrieving an objective track based on such a number of tracks as a special number of tracks added to a difference between an address of a present track and an address of the objective track. CONSTITUTION:A prescribed track is accessed by an optical head 18 with a linear motor 19, and a track address is read out by a controller circuit 28 with an index information read circuit 26. A setting value is obtained in the circuit 28 by adding the difference between the present track address and the objective track address to a number as a multiplication of a number of group boundaries between the present track and the objective track by the number of the special tracks. Then, a linear motor driving circuit 20 is set at this setting value, and the objective track is retrieved by moving the motor 19. By this method, the retrieval error owing to the special track is prevented with minimum constitution.

IPC: H02H3/16
Filed: 1989-11-24
Abstract: PURPOSE:To enable normal leakage only due to a sine wave, to be detected by taking the output in the positive direction and the output in the negative direction, of a leakage detecting means, with same polarities, separately out of the output of a DC voltage multiplexing means, to generate leakage signal under the condition of the existence of both the output amounts, and by interrupting a main circuit interlocked with the function of a switching element. CONSTITUTION:Output from a leakage detecting means 1 is amplified by an amplifying means 5, and by a DC voltage multiplexing means 6, DC voltage is added and after that, both the directional output amounts in the positive direction and the negative direction, of the leakage detecting means 1 are detected separately from the output of the DC voltage multiplexing means 6, with same polarities, and the existence of the output amounts is discriminated. Then, under the condition of the existence of both the directional output amounts, by output from a leakage signal output means 12 for generating leakage signal, a switching element 14 is operated and a main circuit is interrupted. As a result, the device is not operated by signal only in one direction, such as lightning, and normal leakage only due to a sine wave can certainly be detected.
