Abstract: Die vorliegende Erfindung stellt einen Controller zum Steuern der Interrupt-Verarbeitung in einem Mehrfach-Interrupt-System (FIG. 2) bereit. Der Controller 100 enthält: mehrere Watchdog-Zeitgeber (WDTs) 21 bis 23, die jeweils für jede von Interrupt-Prioritäten bereitgestellt werden; Interrupt-Prioritätsselektoren 11 bis 13, von denen jeder jedes Interrupt-Anforderungssignal empfängt und ein Aktivierungssignal an einen entsprechenden WDT ausgibt gemäß der Priorität des Interrupt-Anforderungssignals; und eine Interrupt-Verarbeitungsschaltung 31, die, wenn ein WDT das Zeitlimit überschritten hat, an einen Prozessor ein Interrupt-Anforderungssignal mit einer Priorität ausgibt, die eine oder mehr Ebenen höher ist als die Priorität, die dem WDT entspricht. Wenn mehrere Interrupt-Ursachen einer der Interrupt-Prioritäten zugewiesen werden, räumt die Interrupt-Verarbeitungsschaltung Priorität für ein Interrupt-Anforderungssignal ein, das durch die Zeitlimitüberschreitung eines WDT mit einer niedrigeren Prioritätsebene als die Interrupt-Priorität verursacht wurde, um zu erkennen, dass ein anormaler Betrieb in einer Interrupt-Verarbeitung aufgetreten ist, die die niedrigere Ebenenpriorität hat.

Abstract: PROBLEM TO BE SOLVED: To provide a tape storage device having an optimum additional writing method. SOLUTION: The tape storage device includes: a buffer storing data about read and additional writing; a tape in which the data stored in the buffer is recorded; a reading/writing head which reads data from the tape to the buffer and writes data from the buffer to the tape; and a control means for reading data from a designated position of the tape in response to the read command and storing the data into the buffer, and in response to the additional writing command, writing the data stored in the buffer from a data write additional data terminal position of the tape. A nonvolatile memory storing data stored in the buffer by the write command is provided, data stored temporarily in the nonvolatile memory is moved by the prescribed judgement criterion to a tape write position where the data is to be written so that movement distance which the tape travels for the head becomes the minimum, and thus write is executed.

Abstract: PROBLEM TO BE SOLVED: To shorten a time required for a moving operation of a tape medium in writing data to a tape medium.
SOLUTION: In a controller 16 of a tape drive, when a command processor 41 receives a command for moving to the end of data (EOD) or the like, an operation signal output unit 45 suspends the moving of a tape and a cartridge memory (CM) input/output unit 44 stores therein a state of the tape in which the moving has been omitted. Then, when the command processor 41 receives a command for writing data in this state, the CM input/output unit 44 writes the data to a cartridge memory. Subsequently, for example, when a head passes a proper position at which the data should be actually written to the tape, the CM input/output unit 44 reads the data from the cartridge memory, and a channel input/output unit 43 writes the data to the tape at the proper position.

Abstract: Provided is a tape storage device having an optimal write method even when an overwrite operation is introduced during a combined read/write operation. When the overwrite position of data on a tape is upstream of the end position of write-once data on the tape, the overwrite data position is updated as the end position of the write-once data; and when the overwrite position of the data on the tape is downstream of the end position of the write-once data on the tape, the overwrite data position is updated as the end position of the write-once data in a non-volatile memory (EOD in memory). This allows the overall performance of the combined operation to be improved in the tape storage device even when an overwrite operation is introduced in a command string in which reading and once-writing from a higher-level device are combined together.
