SU1660034A1 - Method for program files retrieval from magnetic tape - Google Patents

Description

The invention relates to computer technology, and in particular to methods of recording and searching for computer program files or data on a magnetic tape. The purpose of the invention is to accelerate and simplify the search for recorded files. Audio tape numbers and / or text signals with continuous numbering are pre-recorded on the tape, between which then files are recorded. Files are searched during trial playback until the required sound signal is found.

The invention relates to computer technology, and in particular to methods of recording and searching for computer program files or data on magnetic media, such as magnetic tape.

The aim of the invention is to accelerate and simplify the search for recorded files.

The proposed method consists in the following.

Before recording computer programs on a magnetic tape, for example, a number of numbers, for example, a natural series: 1, 2, 3, 4, 5, 6, etc., are recorded with a voice through a microphone.

With the duration of the sound of one side of a compact cassette with a film equal to 30 minutes, you can manage to record about a thousand numbers.

First, a reference recording should be made by means of normal dictation, and then the reference recording is copied to all new tapes with a film intended for storing and long-term storage of computer programs.

Before recording a computer program, you must skip at least one number in playback mode, i.e. do not erase the phonogram of at least one number on a small segment of the film. It is more practical to leave two, three numbers. These numbers (or one number) must be recorded in the catalog of this cassette along with the name of the program to be memorized.

Suppose that on one side of a compact cassette with a duration of 30 min there are 10 files recorded (programs or data, etc.), starting, for example, with the following numbers: 2, 104, 200, 250, 320, 637. 699, 718.811, 867,895,936.

Knowing that approximately 1000 numbers fit on this film, you can approximately rewind the film in accordance with the specified number from which the necessary file begins, and, feeling with the help of successive samples, where the voice with this number sounds, continue to download the necessary file to the computer .

When re-writing files to have

busy film is necessary to mark it again.

The method of searching files on a tape provides the following advantages. It eliminates the need for a mechanical counter in a tape recorder, as well as the need to record the name of a file with a voice from a microphone, although this can be done by leaving a number. Speed up the search for the desired file. Simplified equipment.

Even if there is a counter in the micro 1, it has the advantage that when you use it, you can start searching for the file you need from any position of the film in the cassette, you do not need to rewind the film to the beginning to set the counter to zero, and 1 also eliminates the effect of failure to work the counter.

In the future, it is possible to automate the search for the desired file by recognizing the sound signal, i.e. numbers, 2 spoken by a voice or recorded using an automaton synthesizing the sound of word-numerals or the alphabet or other different semantic units that make up a sequence that can be recognized in a two-dimensional work.

Recording of phonograms with numbers on all magnetic films intended for recording computer files can be organized.

Absolutely all cassettes can be laid out at the manufacturing plants, since when recording any phonograms to cassettes it is convenient to start each fragment from a certain marked place (from a specific number or number). You can also calculate the length of the fragment.

The markings on both sides of the film 4 can be made through, i .e. the beginning of the second side is a continuation of the first side. For example, on the first side, numbers from 1 to 1000 are written, and on the second, from 1001 to 2000, etc. four

Through the markup can be done on multiple films, which is convenient for the user, recording the same type of material on multiple films, In this case, he never confuses fragments.

• For pass-through recording, you can make a machine (programmatically) by typing a few dozen words into a computer.

It is not necessary to use only numbers and numbers for marking. You can, for example, use letters, words, etc., as well as a combination of letters and numbers, letters and words, words and numbers. For example, a-1, a-2, a-3 ... a-326, 6-5807, .... satellite-1, satellite-2, ..., mars 16, mars-20.

To the letters, words, numbers, you can add other special signals, such as a sound tone of a certain frequency, a melody. It is possible to insert some reference or entertainment texts or songs, music, etc. after a certain period.

On a stereo recorder, you can write markup on one of the tracks and never erase it, and on the other track you can record phonograms, computer files, etc.

The markup can be produced in blocks, skipping a certain number of intermediate numbers, for example, write only round numbers: 0, 100, 200, etc. (or at any other interval: 0, 50, 100, 150 m, etc.).

Claims (1)

Claim A method for searching recorded files of programs on a magnetic tape, consisting in sequential recording of data blocks of the beginning of files and data, files, rewinding and test playback of the recorded data until the playback of the data block of the beginning of the file, which determines the required data file, characterized by In order to speed up and simplify the search for recorded files, data blocks of the beginning of files are pre-recorded on a magnetic tape in the form of a sequence with continuous numbering of numerical and (or text phonogram signals, between which they then record the data of the files, and the search for files is carried out in the process of reproducing the specified phonogram signals in accordance with the sound content of each of them.
