摘要： In a computer system having a computer, a storage system having storage units being coupled to the computer and for storing user data used by the computer, and a backup device being coupled to the computer and the storage system, a backup method is presented for obtaining a backup of the data stored in the storage unit to the backup device. The storage system holds the user data dually in a first and a second storage units. In backing up the user data, a split instruction for releasing the duplex state of the first and the second storage units is sent from the computer to the storage unit. In response to the split instruction, the storage system interrupts the reflection of the update of the user data to the first storage unit onto the second storage unit. Then, a copy instruction for copying the user data held in the second storage unit to the backup device is sent from the computer to the storage system. The storage system operates to transfer the user data inside of the second storage unit to the backup device in response to the copy instruction.

摘要： A data sharing method for use in a computer system provided with a first computer, a second computer and a data storage subsystem for connection with the first and second computers is disclosed. The data storage subsystem has a plurality of memory units and a control unit for controlling the plurality of memory units. The control unit forms a paired state of a first memory unit storing data for use by the first computer and a second memory unit, the paired state being so controlled as to match the contents of the first memory unit and those of the second memory unit. When data used by the first computer are to be used by the second computer, the control unit releases the paired state between the first memory unit and the second memory unit to stop updating of the first memory unit to be reflected in the second memory unit. After that, the control unit re-maps a third memory unit used by the second computer and the second memory unit with each other, and so performs control that the access by the second computer to the third memory unit be made to the second memory unit.

摘要： Count pulses CTP from a counter 15 are supplied to a phase detector 3 through a two-frequency-divider 17 to produce measurement data N.sub.1 representing a difference in phase from a synchronized peak pulses PK. In a subtractor 4, the measurement data N.sub.1 is compensated with error data Ne from a register 13 in order to reduce the number of steady-state phase errors. An internal phase error .DELTA.N produced by the subtractor 4 is supplied to an LPF 5, undergoing compensation processing in a digital filter 7 thereof. The LPF 5 also includes a phase compensator 6 and a period compensator for compensating a control delay experience by the internal phase error .DELTA.N in the digital filter 7. An integer part OPD1 of counter oscillation period data OPD output by the LPF 5 is used for determining an oscillation period of a counter 15 whereas a fraction part OPD2 thereof is accumulated in a register 12 through an adder 11. An error accumulated in a register 12 is transferred to a register 13 and stored therein as error data Ne. Accordingly, the acquisition time is shortened and the number of steady-state errors is also reduced as well.

摘要： In an automatic library system for transportable data storage units, a library storage control reduces the chances of contention for file mounting. The magnetic tape library system 3 includes first read/write apparatus 20 with automatic mounting and second read/write apparatus 30 not requiring automatic mounting. Depending on the utilization of the first read/write apparatus 20, write data is recorded temporarily in a common storage installed in the second read/write apparatus 30. When the utilization of the first read/write apparatus 20 is low, the temporarily stored data is automatically transferred to a data storage unit in the first read/write apparatus 20 in which the data should normally be stored. The handlers and the first read/write apparatus 20 can be used with priority for handling data storage units for read data that require transport from the storage shelf or holder. The apparent number of the read/write apparatus increases by an amount equal to the number of data writes, improving the system throughput.

摘要： A magnetic tape data management method and apparatus is described that reduces the access time for updating and referring to directory data. At the time of accessing data on a magnetic tape loaded in a magnetic tape subsystem, directory data for the magnetic tape is, in response to the completion of the processing of data, recorded in a region located near the place at which the magnetic tape head is positioned at that time, said region constituting a directory data region (DDR). Further, a directory data memory for recording directory data from the magnetic tape is provided in the magnetic tape subsystem, remote from the tape. At the time of accessing data on the magnetic tape loaded in the magnetic tape subsystem, directory data for the magnetic tape processing is, in response to completion of the processing of data, recorded in the directory data memory in the magnetic tape subsystem.

摘要： A magnetic tape drive in a helical scan system can shorten retry operation time. A data signal reproduced from magnetic tape through reproducing heads is supplied to a regenerative signal processing circuit. If an uncorrectable error is contained in the signal, the regenerative signal processing circuit outputs error information to a system controller. Then, the system controller sends a retry instruction to a movable head controller. When receiving the retry instruction, the movable head controller supplies movable head control signals to displacement elements which then displace the reproducing heads along a rotating shaft of a rotary drum for re-scanning an error occurrence data track. This retry operation is repeated until no error is detected. The magnetic tape is run at lower speed or is stopped as required during the repetitive retry operation.
