IPC: G11B20/10
Filed: 1988-01-14
Abstract: PURPOSE:To constantly execute a reading action or a writing action immediately after the completion of a seek action by providing a means to search an objective record and a means to temporarily store read data or data to be written. CONSTITUTION:A record number comparison part 29 compares data read out from a magnetic disk medium 30 by a magnetic disk medium reading part 26 and data stored in a record number storage part 28. When the search action of the objective record is completed by this comparison, a data transfer controlling part 25 starts writing into a data temporary storage part 24 data read by the magnetic disk medium reading part 26 from the magnetic medium 30. The data transfer controlling part 25 transfers the data to be stored from the data temporary storage part 24 to a magnetic disk medium writing part 27 and starts writing into the magnetic disk medium 30. Thus, the reading action or the writing action can be executed immediately after the completion of the seek action.

Abstract: PURPOSE:To shorten the measurement time by monitoring the generation of an abnormal temperature place with the small number of times of averaging and low distance resolution and accurately remeasuring the state of the periphery of the abnormal place with the large number of times of averaging and high distance resolution. CONSTITUTION:A temperature detection part 13 takes a measurement with the irreducible minimum distance resolution and the small frequency of averaging and transfers the data to a microcomputer 11 through a bus line B to monitor the generation of the abnormal temperature place. When it is decided that the place is normal as a result of the monitoring, the movement averaging of averaged data is performed in the microcomputer 11 and the temperature distribution of an optical fiber 16 to be measured is measured with the result and displayed on a display device 12. When it is decided that the place is abnormal, a temperature detection part 13 is switched to the operation with the high distance resolution and the large number of times of averaging and the measurement range is narrowed down to the vicinity of the detected abnormal place, which is precisely remeasured. Consequently, the abnormal point can be detected at a high speed and measured fast and accurately.
