摘要： A tape drive, tape drive recording system, and method are provided for improving tape speed selection during data transfer. The tape drive includes a buffer, a tape for recording the data to be temporarily stored in the buffer, and a read head. The tape drive further includes a reading controller that initially sets a tape speed such that a drive transfer rate matches a host transfer rate as closely as possible and that drives the tape at the tape speed. To address backhitching caused by one or more host transfer halts, the reading controller subsequently adjusts the tape speed such that the drive transfer rate is lower than the host transfer rate by recalculating the host transfer rate in consideration of the host transfer and the host transfer halt and setting the tape speed such that the drive transfer rate matches the recalculated host transfer rate as closely as possible.

摘要： High performance is obtained without preventing achievement of a target read data rate.In a controller 16 of a tape drive, a command processing unit 41 receives a synchronization command, and a buffer management unit 42 passes data in a buffer to a channel input-output unit 43. Then, upon completion of writing the data to the tape, a backhitch determination unit 44 determines whether or not to execute backhitch. If it is determined that backhitch should be skipped, the speed determination unit 46 determines a tape speed that minimizes a sum of a time required to write data without backhitch within a range where a data amount of a monitor target is to be written in order to achieve a target read data rate, and a time required to write data with backhitch within the range. Then, an operation signal output unit 49 issues an instruction to change the tape speed to the determined tape speed after execution of backhitch.

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： A plurality of tape drives writes a plurality of indicators corresponding to a plurality of data units on a tape, wherein an indicator indicates which tape drive of the plurality of tape drives has written a corresponding data unit on the tape. Each of the plurality of tape drives generates an extent of read errors, in response to reading the plurality of data units written on the tape. The extent of read errors generated by each of the plurality of tape drives are aggregated at a computational device coupled to the plurality of tape drives. A determination is made at the computational device of a defective tape drive of the plurality of tape drives from the aggregated extent of read errors.

摘要： In a controller of a tape drive, when a command processing unit receives a Write FM0 command, a channel input/output unit writes the data in the buffer and a speculative FM onto the tape, and a CM input/output unit records speculative FM presence information in a cartridge memory. When the command processing unit receives Write FM1 command next, the CM input/output unit erases the speculative FM presence information from the cartridge memory. When the command processing unit receives a command other than Write FM1 command next, the channel input/output unit overwrites a speculative FM.

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.
