摘要： An apparatus for measuring a terahertz wave includes a dispersing section 103 for chirping the terahertz wave 104 generated from a generating section 101. A detecting section 102 detects waveform information on the terahertz wave chirped by the dispersing section 103. As a result, it is possible to acquire frequency information included in the waveform information. Therefore, it is possible to acquire spectral information including amplitude information of each frequency component and intensity information on each frequency or wavelength from the time waveform without Fourier-transforming the time waveform.

摘要： The present invention enhances the capability to specify a recorded position of designated data, even when a tape medium is run at high speed. A controller of a tape drive includes: a data set generator for generating a data set; a metadata generator for generating metadata including the number of records in the data set and the like; and a writing unit for writing the data set to the tape medium with a high recording density, and writing the metadata to the tape medium with a low recording density. The controller also includes: a movement controller for receiving a record number of a designated record; a reading unit for obtaining the number of records and the like included in the metadata read by running the tape medium at high speed; and a comparison unit for determining whether or not to read the data set by lowering the speed of the tape medium to R/W speed, in comparison with the record number received by the movement controller and the number of records and the like obtained by the reading unit.

摘要： A method to write information to a tape storage medium by disposing a tape storage medium in a tape drive apparatus comprising a write head. The method moves the tape storage medium in a first direction, writes data from a buffer to the tape storage medium, and thereby empties the buffer while the tape storage medium is moving in the first direction. The method determines, while the tape storage medium is moving in the first direction, whether to enable a backhitchless write wherein the tape storage medium is not stopped and moved in a second and opposition direction, prior to writing new data to the tape storage medium. By not stopping the movement of the tape storage medium, and by not moving the tape storage medium in a reverse direction to reposition the write head, the method eliminates the time overhead required to stop the tape and reposition the tape head. Applicants' method achieves this time efficiency without adverse impact to the nominal storage capacity of the tape information medium.
摘要翻译：一种通过将带存储介质配置在包括写入头的带驱动装置中来将信息写入磁带存储介质的方法。该方法使磁带存储介质沿第一方向移动，将数据从缓冲器写入磁带存储介质，从而在磁带存储介质沿第一方向移动时清空缓冲器。该方法在磁带存储介质在第一方向上移动时，确定在将新数据写入磁带存储介质之前是否启用磁带存储介质在第二和相对方向上不停止和移动的无间隙写入。通过不停止磁带存储介质的移动，并且通过不使磁带存储介质沿相反方向移动以重新定位写入头，该方法消除了停止磁带所需的时间开销并重新定位磁带头。申请人的方法实现了这种时间效率，而不会对磁带信息介质的标称存储容量产生不利影响。
