摘要： First characteristic information indicating a characteristic of input data is extracted from the input data that is input as data to be stored in any of the storages. Second characteristic information elements are read from a memory unit storing the second characteristic information elements indicating respective characteristics of stored data elements stored in the storages. A specific storage in which the input data is to be stored is determined, out of the storages, by determining a degree of match between the extracted first characteristic information and the second characteristic information elements read. The input data to the determined specific storage is read. The second characteristic information element indicating the characteristic of the stored data element stored in the specific storage is updated, out of the second characteristic information elements retained in the memory unit, on the basis of the extracted first characteristic information.

摘要： In a controller of a tape drive, a CM input-output unit recognizes a tape format; a tape variable acquisition unit acquires tape variables; a setting variable acquisition unit acquires setting variables; and a minimum number calculator calculates a minimum number m of sub datasets, which are to be written to a tape to secure resistance to burst error, by using the tape variables and setting variables. When a command processor receives a synchronization command, the buffer manager generates n sub datasets for storing data in the buffer. If n is smaller than m, m sub datasets are padded out and set as write data. If n is m or more, the n sub datasets are set as write data. Then, the channel input-output unit writes the write data to the tape.

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.
