Abstract

PURPOSE:To improve the rigidity of a master tape and to rapidly execute the dubbing of much narrow tape by using an endless master tape wider than a slave tape. CONSTITUTION:The master tape MT is a wide and endless tape whose width is about twice that of the slave tape ST. The tape MT is drawn from a tape storage part 11c by a master tape traveling mechanism 10 and returned to the storage part 11c again through a tape adhering mechanism 30. Since the tape MT is wide and firm, the tape MT is correctly folded in the storage part 11c. Since the tape MT is prevented from being twisted or entangled in the storage part 11c, the tape MT can rapidly be traveled. On the other hand, the tape ST from a feeding reel 21 is sent from the reel 21 to a winding reel 22 by a sledder traveling mechanism 20 through the adhering mechanism 30. At that time, the contents of the tape MT are transferred to the tape ST by the mechanism 30.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a magnetic tape dubbing device, and more particularly to a transfer type dubbing device that transfers a master tape and a slave tape in close contact with each other, and its master tape.

(Prior art) Conventional dubbing technology involves running the magnetic media surfaces of a master tape and a slave tape in close contact with each other, and applying an external magnetic field or heat to the closely contacted portion. A transfer-type dubbing device is generally known, which performs transfer using two normal VTRs.
Because dubbing is approximately 400 times faster than when a playback device such as , special public official 1977

) is run by running it between a pair of reels.

(Problems to be Solved by the Invention) In the transfer type dubbing device disclosed in Japanese Patent Publication No. 57-3142, the master tape must be rewound onto the supply reel each time dubbing is completed.

During dubbing, the tape can run at about 400 times the normal speed, but if the loss of rewinding is added, the speed becomes about 150 times on average, and the high speed advantage of the dubbing device is halved.

Furthermore, the transfer type dubbing device disclosed in JP-A No. 63-104253 has the advantage of greatly increasing the dubbing speed and is preferable; On the other hand, tapes with a small width such as those for audio tapes and R-DATs are not preferable because they are weak and lack rigidity, and there is a risk that the master tape may become tangled.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide an apparatus and a master tape for dubbing narrow tapes such as audio tapes at high speed and in large quantities.

(Means for Solving the Problems) In order to achieve the above object, the present invention forms a master tape wider than a slave tape into an entresive tape, and includes a master tape running mechanism for running this tape, and a supply reel to winding tape. A transfer type dubbing device is composed of a slave tape running mechanism that runs a slave tape between reels, and a tape adhering mechanism that brings both the mask and slave tapes into close contact.

Furthermore, by forming multiple recording tracks on a wide master tape and attaching multiple slave tape running mechanisms to one master tape running mechanism, it is possible to transfer data to multiple slave tapes at the same time. .

Furthermore, by making the endless master tape wider, the master tape is made stronger and its rigidity is increased.

(Function) The wide endless master tape has the required rigidity and is correctly folded into the tape storage section during circulation.

Note 8 for dubbing the upper or lower half of a wide master tape in the width direction or multiple strips in the width direction! Tracks are recorded, and one or more slave tapes are brought into close contact with these recording tracks to perform transfer.

(Example) Embodiments of the present invention will be described below based on the accompanying drawings.

The master tape MT has two tapes on the top and bottom as shown in FIG.
Tracks TI and T2 of the row are recorded.

Therefore, in the fourth embodiment, as in the third embodiment, transfer can be performed to two slave tapes at a time. Moreover, in the fourth embodiment, the slave tape running mechanisms 20C and 20D are stacked one on top of the other, so compared to the third embodiment, the device can be made much more compact and the drive means for the slave tape running mechanisms can be shared.

It is also possible to transfer to a slave tape larger than a book.

(Effect of the invention) As described above, the present invention has the following effects.

(2) Since the master tape is made wide and given the necessary rigidity, the endless transfer type dubbing device can also be used to transfer narrow magnetic tapes.

(2) Since a plurality of tracks are formed on the master tape in the width direction, it is possible to simultaneously transfer data from one master tape to a plurality of slave tapes.

(2) Since a plurality of tracks are formed on the master tape in the width direction, by recording different software on each track, it is possible to transfer a plurality of software at the same time.

(2) Particularly in the case where a plurality of slave tapes are coaxially supported and run at the same time, the part in close contact with the master tape is on the same axis, making the configuration very simple.
