Abstract

PURPOSE:To execute a high-density recording on a magnetic stripe face imparted with a high coercive force by independently providing a recording gap and a reproducing gap, and setting each gap width to be suited to a recording processing for a high coercive force. CONSTITUTION:Two exclusive gaps having different gap width, that is, a recording gap 14 and a reproducing gap 15 are independently provided at one magnetic head 11. Then, when a magnetic card 19 is guided to the corresponding position of the head 11, the head 11 is moved to a prescribed data processing position by a moving mechanism 18. Thus, even when a magnetic stripe face 20 of the card 19 is imparted with a high coercive force, the width of the magnetic gaps 14 and 15 are set to be suited to the recording and reproducing processing for the high coercive force so that the high density recording on the magnetic stripe face imparted with a coercive force can be stably operated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus for recording / reproducing magnetic data on a magnetic medium such as a magnetic card, and more particularly to a magnetic recording / reproducing apparatus having an improved recording / reproducing performance of magnetic data.

[0002]

2. Description of the Related Art A magnetic card will be described below as an example. Generally, when recording and reproducing magnetic data of a magnetic stripe formed on a magnetic card with a magnetic head,
In order to improve the safety of magnetic data, a magnetic stripe with high coercive force is required. In this case, it is necessary to deal with the high coercive force on the magnetic head side as well.
As shown in FIG. 6 and FIG. 6, the recording / reproducing process is performed by using the single gap combination head formed by providing the predetermined gap 53 between the wide recording core 51 and the narrow reproducing core 52. .

[0003]

However, in order to perform highly secure and reliable recording, it is necessary to set the gap on the recording core side to a sufficient width suitable for high density recording. However, because of this single-gap combination head configuration, the gap on the other reproducing core side is limited, and the gap on the recording core side cannot be set to an optimum value. Recording / playback was not possible. Further, it is conceivable to use two dedicated magnetic heads, a recording-only head and a read-only head, side by side, but in this case, there is a problem in that the apparatus becomes uneconomical and the apparatus becomes large. Therefore, an object of the present invention is to provide a magnetic recording / reproducing apparatus that can set a recording gap to an optimum value and stably perform high-density recording on a magnetic card having a high coercive force.

[0004]

According to the present invention, magnetic data of a magnetic medium is recorded / reproduced by associating a recording gap and a reproducing gap of a magnetic head provided on a magnetic medium conveying path with a magnetic surface of the magnetic medium. A magnetic recording / reproducing apparatus for processing, wherein a recording gap and a reproducing gap formed in the magnetic head are arranged side by side in a width direction of a magnetic medium conveyance, and the recording gap is formed by a magnetic gap of a magnetic medium when recording the magnetic data. The magnetic head moving means is provided so as to correspond to the surface and the reproducing gap corresponds to the magnetic surface of the magnetic medium when reproducing the magnetic data.

[0005]

According to the present invention, when the magnetic data is recorded, the magnetic head moving means moves the magnetic head to make the recording gap correspond to the magnetic surface of the magnetic medium, and when reproducing the magnetic data, the magnetic head moves. Means moves the magnetic head to cause the reproducing gap to correspond to the magnetic surface of the magnetic medium.

[0006]

As described above, since the recording gap and the reproducing gap are separately arranged side by side, only the recording gap corresponds to the recording on the magnetic medium and only the reproducing gap corresponds to the reproducing. As a result, the gaps on both sides can be set to a width suitable for recording / reproducing processing for high coercive force, resulting in a magnetic surface with high coercive force. The high-density recording can be stably performed, and the device can be downsized more reliably and economically as compared with the case where two dedicated magnetic heads are used together.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below with reference to the drawings. The drawings show a magnetic recording / reproducing apparatus provided with a magnetic head for performing magnetic recording / reproducing processing of a magnetic card. In FIGS. 1 and 2, the magnetic head 11 is provided with projecting terminals 12 ... A recording gap 14 dedicated to magnetic recording and a reproducing gap 15 dedicated to magnetic reproduction are provided on the lower surface 13 corresponding to the magnetic contact. The above-mentioned gaps 14 and 15 are separately arranged side by side on one side and the other side in the carrying width direction of the magnetic card, and the recording gap 14 on one side has a wide width having the same width as the magnetic stripe width. Formed between the recording cores 16 and 16,
The gap between the facing cores 16 and 16 is formed to have a relatively wide gap suitable for high-density magnetic recording processing on the magnetic stripe surface having a high coercive force. Further, the reproducing gap 15 on the other side has a narrow reproducing core 1
7 and 17, the cores 17 and 1 facing each other are formed.
The width of the gap between 7 is formed so as to have a predetermined gap suitable for high-density magnetic reproduction processing of the magnetic stripe surface having a high coercive force. Further, the magnetic head 11 has a structure shown in FIG.
Further, as shown in FIG. 4, the magnetic head moving mechanism 18 allows the magnetic card 19 to move horizontally in the conveying width direction. The magnetic head moving mechanism 18 makes the recording gap 14 correspond to the surface of the magnetic stripe 20 of the magnetic card 19 at the time of recording to write the magnetic data, and sets the reproducing gap 15 to the magnetic card 19 at the time of reproducing to read the magnetic data.
The two gaps 14 and 15 are used in correspondence with the surface of the magnetic stripe 20 for recording or reproducing. For this reason, it is possible to effectively use the two dedicated gaps having different gap widths, that is, the recording gap 14 and the reproducing gap 15, independently of each other, though it is one magnetic head 11.

A case where magnetic recording / reproducing processing of a magnetic card is performed using the magnetic recording / reproducing apparatus having the above-described structure will be described below. Now, when the magnetic card 19 is conveyed and guided to the corresponding position of the magnetic head 11, the magnetic head 11
Is previously moved to a predetermined data processing position according to the recording / reproducing process by the magnetic head moving mechanism 18. For example,
As shown in FIG. 3, during recording of magnetic data, the magnetic head 11 is moved by a predetermined amount in the carrying width direction to move the recording gap 14 so as to correspond to the magnetic stripe 20 surface of the magnetic card 19, and FIG. As shown in FIG. 5, when reproducing the magnetic data, the magnetic head 11 is moved in the carrying width direction by a predetermined amount to set the reproducing gap 15 so as to correspond to the magnetic stripe 20 surface of the magnetic card 19. As a result, the magnetic card 1 carried into this magnetic processing position
9 shows that even if the surface of the magnetic stripe 20 has a high coercive force, both gaps 14 and 15 are recorded for high coercive force.
Since the width is set to be suitable for the reproducing process, high-density recording can be stably performed on the surface of the magnetic stripe 20 having the high coercive force.

As described above, since the recording gap and the reproducing gap are separately arranged side by side, only the recording gap is made to correspond when recording on the magnetic card.
At the time of reproduction, it is possible to adopt an individual correspondence structure in which only the reproduction gap is made to correspond. As a result, the gap width suitable for the recording process for high coercive force can be set to stably perform high-density recording on the magnetic stripe surface with high coercive force, and two dedicated magnetic heads. Compared with the case where the two are used together, it is economical and the device can be surely downsized.

In the correspondence between the present invention and the configuration of the above-described one embodiment, the magnetic head moving means of the present invention corresponds to the magnetic head moving mechanism 18 of the embodiment, and hereinafter, similarly, the magnetic medium is a magnetic card. 19 and the magnetic surface corresponds to the magnetic stripe 20, but the present invention is not limited to the configuration of the above-described embodiment.
