- the module has at least one magnetic recording head elementary near which the recording element moves.
- the basic recording head generally consists of a electro magnet.
- Each of the elemental heads generates, whenever it is excited by an electric current of determined intensity, a field magnetic which has the effect of creating, on the surface of the element of recording which scrolls past these elementary heads, domains magnetized small. These practically magnetized domains punctuals are generally referred to as points magnetized recording.
- the portion of the surface of the element that passes in front of each head is usually referred to as tracks information recording.
- Magnetized recording points located on the same track of recording and preceded in the direction of scrolling of the element to register at least one registration point that has not been magnetized belong to a set of recording points magnetized called the leading edge.
- the juxtaposition of the recording points forms an image. Of magnetic ink particles are then attracted to the dots tape magnetized on the recording element. A paper print is pressed against the recording element. Ink particles are transferred and fixed on the paper: the image formed by the recording points on the drum is transferred using particles magnetic ink on the paper.

- the drum 3 is driven in rotation on itself by an electric motor in a direction designated on the designs with the letter S.
- the surface portion of the drum 3 which runs in front each head is called recording track 4 (see Figure 2).
- the elementary head 2 receives electrical signals representative of data sent by a control unit 5 represented by a box black in Figure 1.
- the elementary magnetic heads record the data received from unit 5 in the form of recording points 6 on the drum 3.
- the signals units of unit 5 consist of current pulses I transmitted to the elementary magnetic head 2.
- the magnetic field induced by pulses created on the surface of the drum 3 which passes in front of the heads 2 of the magnetized recording points 6 shown in Figures 2, 3, 6 to 9.
- a magnetized recording point is form.
- All the recording points on the surface magnetic recording of the drum 3 corresponds to the image that one wish to print on paper.
- the image comes in various forms, drawings, character string, photo ... or any other likely form to be reproduced by printing.
- the image is saved in the printer in the form of a matrix of points arranged in line and in column.
- the points of the matrix will be called in the following points of image for them distinguish recording points 6.
- Image points are white or black. Black dots should be printed.
- the horizontal definition of the image is a function of the distance between two magnetic heads 2 elementaries arranged on the same line.
- the vertical definition corresponds to the step between two lines.
- the pulses are emitted periodically.
- the period of time between two pulses corresponds to the time taken by the drum to cover the distance equal to not between two lines of the image.
- the time period is chosen from so that the vertical definition keeps the same determined value whatever the rotation speed of the drum 3.
- each point image corresponds to a recording point.
- Registration points magnetized 6 correspond to determined black image points, the recording points not magnetized to white image points.
- the recording points are at the intersection of a line given by the position of the drum 3 and of a column given by the position of the head 2 elementary magnetic. The column corresponds to the recording track 4.

- Three successive current pulses are transmitted to head 2 magnetic element next to track 4 recording in question.
- the ink particle When the second magnetized recording point 6B passes in front of the ink particle 7, the ink particle has already benefited from the work provided by the first magnetized recording point 6A.
- the energy of the ink particle is supplied by the work T of the magnetic developing force.
- the work is therefore equal in a frame of reference (y, z) linked to the drum 3 to: y being the tangential component of the frame of reference and z the diametral component; b corresponding to the length tangential to the drum between the center of the magnetized recording point and the end thereof; T 1 being the work provided by the first magnetized recording point.
- Magnetized recording points not belonging to the edge are better revealed than those at the leading edge because they benefit of the work of the magnetic development force of the points magnetized recording that precedes them.

- the set of leading edges of distance n and of order m is denoted BAD n O m .
- leading edge BAD n O m is included in the leading edge BAD n-1 O m which is itself included in the leading edge BAD n-2 O m and so on to the edge d BAD attack 1 O m .
- Two recording points or image points are contiguous if they are found on two successive lines separated by a step.
- Figure 5 shows the leading edge of the blackened image, while the other image points are grayed out.
- the detection means 9 operate in the following manner: the storage means 9A store a number n + 1 of lines of image points. Means of comparison compare in real time the last of the n + 1 lines stored with the n lines of image points stored column by column to detect points image of the leading edge.
- the control unit 5 is in connection with the detection means 9: the results of the comparison are transmitted to the control unit.
- the comparison made and transmitted, the means 9A of storage deletes the last of the n + 1 lines stored in the time and stores the next line in the direction of rotation of the drum.
- the comparison means compare said next line to n other lines stored and so on.
- the storage means 9A store a new line while simultaneously the comparison means 9B work on the n + 1 lines stored as described above.
- the component programmable works as follows: a line of dots image is stored in memory 9A.
- the point line is written in the memory line i modulo 4.
- line (i-1) modulo 4 is compared to lines (i-2) modulo 4 and (i-3) modulo 4. If an image point black of the line (i-1) modulo 4 is preceded by two white dots of the lines (i-2) modulo 4 and (i-3) modulo 4, the black image point in question of the line (i-1) modulo 4 is part of the leading edge.
- Detection means 9 indicate to the control unit 5 that the black image point in question is a point on the leading edge. Then the next point line is processed from the same way by incrementing the value of i by 1.
