Embodiment Construction

[0029] An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing an example of a system configuration according to an embodiment of the present invention. A sequential recording / reproducing apparatus 100 (hereinafter referred to as recording / reproducing apparatus 100) records data to or reproduces data from, for example, a volume composed of a sequential recording medium such as a magnetic tape. The recording / reproducing apparatus 100 is connected to a computer system such as a personal computer or a file server. The computer system includes a CPU 101 and a hard disk drive (HDD) 105 connected thereto, as shown in FIG. 1 . The recording / reproducing apparatus 100 records data to or reproduces data from the volume 106 corresponding to an application running on the CPU 101 .

[0030] 2A and 2B are diagrams showing examples of data formats on magnetic tape used in conjunction with the system. Referring...

Abstract

At the start of a volume comprising a magnetic tape, a start volume label including volume identifying information is provided. After the start volume label, a batch file, which is the data body, is provided. At the end of the volume, an end volume label having the same contents as those of the start volume label is provided. When the volume is mounted, one of the start and end volume labels, which is the closer one to the seek position, is read. When the volume is unmounted and when the seek position is the end of the data, the end volume label is additionally written. Since the volume label is written at the two places, the mounting operation is speedily carried out, and the reliability of media is enhanced.

Description

technical field [0001] The present invention relates to a recording device, a recording method, a reproducing device, a reproducing method, and a recording medium capable of high-speed readout of a volume label of a recording medium (such as a magnetic tape) on which data is sequentially recorded and reproduced. . Background technique [0002] In computer systems, a data library has been implemented using a changer device that accommodates many tape cartridges. In this tape changer device, several tens to several hundreds of tape cassettes are placed in designated positions in bins. Furthermore, at least one recording / reproducing device (tape drive) is built in the tape changer device. The tape changer device is connected to a host computer that operates with UNIX as an OS (Operating System) through SCSI (Small Computer Interface) as an interface. [0003] The host computer has a database (database) for managing the data library. The database contains information about t...
