 a time of occurrence of disaster.
According to studies conducted by the inventors of the present invention, the following techniques are available to a conventional copy processing technique for the data processing system.
For example, in recent years, in order to always provide continuous services to a client, the data copying technique among a plurality of disk array devices have been suggested so that the services can be provided even when failure occurs in the disk array device such as a storage device for storing data. Particularly important is a technique for continuing and restarting data copying among remote sites and data copying at the time of failure. An example of a technique used in a data processing system having a plurality of disk array devices for copying, to second and third disk array devices, information stored in a first disk array device is disclosed in Patent Document 1 (U.S. Pat. No. 6,209,002).
In the Patent Document 1, a disk array device is provided to each of a local/production site, a first remote site, and a second remote site. Among these three disk array devices, the disk array device at the local/production site transfers data stored therein to the disk array device at the first remote site for copying. Then, the disk array device at the first remote site stores the transferred data and also transfers the data to the disk array device at the second remote site. Then, the disk array device at the second remote site stores the transferred data. Thereby, the technique for making the data redundant is disclosed. 1. Field of the Invention
The subject invention relates to oscillography and oscillographs and other recording methods and recorders, to methods and apparatus for supplying wound material from rolls of diminishing diameter and other winding and reeling methods and apparatus, to methods and apparatus for releasably retaining any one of several tubular objects of different lengths, and to combinations of such methods and apparatus.
2. Description of the Prior Art
An advanced type of record medium transport mechanism is disclosed in U.S. Pat. No. 3,216,021. That apparatus appears able to handle reporting medium strips wound on a supply roll and having an information recording surface layer either facing inwardly or outwardly on the supply roll. Also, that apparatus appears capable of winding the recording medium strip, after recordation thereon, on a takeup roller, or then of discharging such recording medium strip from the machine. To this end, that prior-art apparatus has a drive roller with gearing shiftable between different positions, as well as a shiftable front

 According to report behave by the inventors of the present invention, the following techniques are available to a ceremonious copy processing technique for the data processing arrangement. 
 For example, in recent old age, in order to always leave continuous services to a client, the datum copying technique among a plurality of phonograph record array devices have been suggested so that the service can be provided even when failure occurs in the magnetic disk array device such as a storage device for storing data. Particularly significant is a technique for continuing and restarting data copying among remote web site and data copying at the time of failure. An example of a technique used in a data processing system having a plurality of disk array devices for copying, to second and third disk array devices, information stored in a first phonograph record array device is disclosed in Patent Document 1 (U.S. Pat. No. 6,209,002). 
 In the Patent Document 1, a magnetic disk array device is provide to each of a local / production site, a first outside web site, and a second remote site. Among these three disk array device, the disk array device at the local / production site transfers datum stored therein to the disk array device at the first remote site for copying. Then, the disk array device at the first distant site stores the transferred data and also transmit the data to the disk array device at the second remote web site. Then, the disk array device at the second outside site stores the transfer data. Thereby, the technique for making the data redundant is unwrap. 1. Field of the Invention
