Title: Information recording and reproducing device
Inventor: OGINO YOSHITAKA
IPC: G11B27/10
Filed: 1990-05-17
Abstract: PURPOSE:To eliminate a useless seek operation and to enable an optical head to seek a target in its nearer position by correcting an error due to rotation of a recording medium during a moving time of the optical head. CONSTITUTION:First, a comparison is made between a target track address to be sought and a track address where the optical head 3 is presently positioned. As a result of this comparison, if they are not equal to each other, their difference is calculated from absolute values of the target track address and the present positioning track address as a 1st relative value T1. Secondly, in order to obtain an error during th moving time of the optical head 3, a calculation is made to evaluate a 2nd relative value T2. Then, a position of a target sector address and an arrival position after seeking are compared with each other, and if the target position is below the arrival position after seeking, a parameter P is decided as -1. On the contrary, if the target position is larger than the arrival position after seeking, the parameter P is set as 0. Then, such obtained T1, T2 and P are added up to find and execution relative number T, and based on an obtained result, the seek operation is executed.

Title: Production of optical fiber coated with metal
Inventor: KOUMURA YUKIO
IPC: G02B6/44
Filed: 1981-08-12
Abstract: PURPOSE:Optical fiber coated with a plastic is fed into the common vacuum zone, heated to remove the plastic coating and subjected to vacuum plating, thus enabling the control of the coating thickness by the line speed. CONSTITUTION:Optical fiber coated with a plastic 8 is fed through the prevacuum chamber 9 into the first vacuum chamber 1 where the plastic coating is removed by burning off with the radiation heat from heater 6. The resultant fiber 8' is passed through the vacuum chamber connector 3 to the second vacuum chamber 2 where the fiber is plated by means of the vacuum plating unit 7. After plating, the resultant fiber 8'' comes out of the vacuum chamber 2, passes through the auxiliary vacuum chambers 10, 11, then is wound up. Thus, the melt-spinning and the vacuum plating are effected independently and it is unnecessary to synchronize the melt-spinning speed with that of vacuum plating line, so the thickness of the plated layer is controlled with the line speed.
