Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to magnetic tapes (hereinafter referred to as program tapes) on which computer programs such as personal computers (hereinafter referred to as personal computers) are recorded;
The present invention also relates to a computer program tape duplication method and apparatus for directly inputting and duplicating computer programs such as personal computers.

FIG. 1 is a diagram showing the conventional program duplication process,
Program information on a computer 1 such as a personal computer is converted into an analog format, for example, and outputted to the Arashi Inch Recorder 2, where a plurality of program information 1-N are sequentially recorded on one track as shown in FIG. 2(A). Original tape 3 is created. The program information 1 to N recorded on the original tape 3 is played back by the inch recorder 2 and later output to the inch recorder 4. The station inch recorder 4 edits the plurality of program information sent in this way, such as changing the order and deleting them, and stores the program information 1 on two tracks as shown in FIG. 2(B).
-N and 1' to N' are recorded on the master tape 5. The program information of this master tape 5 is simultaneously played back at high speed on both tracks by the master player 6 and several slave recorders connected in parallel. (71-7n), and a large number of duplicate tapes 8 (81-8n) are created here.

In such a conventional method, digital information in the form of a computer program is once recorded on an original tape 3 in analog or digital format, and then recorded on a duplicate tape 8 via a master tape 5 prepared by manually editing it.
Since the program information is duplicated in a number of seconds, errors are likely to occur in the time width of the program information, making it impossible to obtain a duplicate tape 8 of higher quality than the original tape 3. In addition, the master tape 5 deteriorates as it is repeatedly reproduced, and a new mask tape 5 must be created after being used approximately 1,000 times.

On the other hand, if the editing process using the master tape is performed by a computer, it is possible to obtain a duplicate tape of higher quality than the original tape, and there is no need to recreate the master tape no matter how many times it is duplicated. Become. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method and apparatus for duplicating a computer program tape in which editing is performed by a computer without creating a mask tape, and recording is simultaneously recorded on all tracks of a plurality of tapes having a plurality of tracks. It is in.

This invention will be explained below.

The program information that is received is input into a copying computer, and the copying computer edits the program information, such as changing the order of the program information, and then transmits the program information at high speed to a copying tape recording means, and then the program information is recorded. When recording on a duplicate tape with multiple tracks, for the tracks of the duplicate tape where the tape running direction during duplication matches the tape running direction during playback, the program information is recorded from the beginning of the program information to the end. For tracks of duplicate tapes where the running direction and the tape running direction during playback are opposite to each other, program information is recorded on multiple tapes simultaneously from the end to the beginning, and
This duplication method is realized by an apparatus.

FIG. 3 shows the process when the method of the present invention is applied to the reproduction of program information of the personal computer 11, in which the program information of the personal computer 11 is converted into an analog format through a suitable output circuit or converted into a digital format. Either the program information is directly outputted to the cassette recorder 12 to create an original tape 13, or the program information from the personal computer 11 is directly inputted to the copying computer 14. in this case,
The same electrical signal as recorded on the original tape 13 may be input to the copying computer 14, such as ""o", '"
In addition, program information from the personal computer 11 can be input to a floppy disk and driver, a perforated tape, and a tape league.

The information is input to the copying computer 14 in digital form via a digital tape, player, or the like. Note that the program information stored on the original tape 13 is played back on the cassette recorder 12 and sent to the copying computer 14.
The data is input into the computer 14, converted into digital format by an input circuit, and then processed in the copying computer 14.

Here, the duplication computer 14 edits the input program information by changing the order, deleting, adding, etc., and outputs the edited program information to several slave recorders connected in parallel as duplication tape recording means. 7 (71~7n)
Output multiple tracks at the same time to the duplicate tape 8 (8
1 to 8n) are produced in parallel. To simultaneously record on all tracks of a duplicate tape with duplicate tracks,
When recording on a track where the tape running direction at multiple times and the tape running direction during playback after duplication match, the program information to be recorded is output from the beginning to the end from the output circuit to the corresponding recording head of the slave recorder. However, when recording on a track in which the tape running direction during duplication and the tape running direction during playback after duplication are opposite, the output circuit of the slave recorder will move from the end of the program information to be recorded to the beginning. Output to the recording head.

Note that this duplicate tape 8 is an open reel tape, and if it is necessary to make it into a cassette tape, a cassette duplicate tape 1G is produced from the duplicate tape 8 by a tellering machine 15.

FIG. 4 is a diagram showing a schematic configuration of a two-track duplication computer 14 used in the present invention, and the program tape recorded by the cassette recorder 12, such as a cassette tape 13, can be recorded on a program tape in analog or digital format, or on a floppy disk.
