[Detailed Description of the Invention] The present invention relates to a magnetic recording and reproducing device for recording and reproducing using a cassette tape, and in particular, a narrow track and a magnetic recording/reproducing device.
In cassette-type magnetic recording and reproducing devices that require very precise tracking and tape touching, such as magnetic recording and reproducing devices that perform short wavelength high-density recording and reproducing using multi-track magnetic heads,
The purpose of this invention is to eliminate variations in head touching and tracking due to the shape of the cassette, the precision of its positioning, or the precision of positioning of the magnetic head, and to enable recording and reproduction of shorter wavelengths with narrower tracks.

A conventional magnetic recording/reproducing device will be explained using FIGS. 1, 2, and 3. In Figure 1,
1 is a cassette, 2 is a magnetic head insertion window in the cassette, 3 is a magnetic tape visible through the insertion window 2, and 4 is a magnetic head. During recording and reproduction, the magnetic head 4 is moved in the direction of arrow A by a moving mechanism (not shown) that responds to recording and reproduction operations, is inserted into the insertion window 2, and comes into contact with the magnetic tape 3. For example, in the case of a device that performs narrow-track, short-wavelength, high-density recording using multi-track, such as a device that magnetically records and reproduces PCM signals, the magnetic head 4 is a second magnetic head.
A thin film head as shown is used. In FIG. 2, the rear is the head tip, which has a gap 6 at the tip. 7 is a head base for fixing the head chip 5, and 8 is a flexible wire for electrically connecting the recording/reproducing head amplifier system and the magnetic head 4. Note that the radius of the tip of the head chip 5 is made small in order to make it easier to obtain output in recording and reproducing short wavelengths, that is, to reduce spacing loss. Such a magnetic head 4 with a small tip radius
When a cassette is inserted into a cassette as shown in FIG. 1 for recording and reproducing using a cassette, the problem of positional accuracy as described below arises because of the narrow multi-track and short wavelength.

FIG. 3 shows the positional relationship between the magnetic head 4 and the magnetic tape 3, and the positional accuracy will be described in detail. B to I are major variables; the angles indicated by arrows B and C are the winding angle of the magnetic tape 3 on the magnetic head 4; the angle indicated by arrow D is the contact angle of the magnetic head 4 with respect to the magnetic tape 3; and the arrow E is The mounting position of the magnetic head 4 in the horizontal direction; These are factors that indicate the amount of tilt. Of course, it can be divided into more detailed factors, but the following explanation will be made using the main eight factors shown in B to I above.

As mentioned above, the tip radius of the head tip 5 of the magnetic head 4 is quite small, and the contact area with the magnetic tape 3 is very small. Therefore, strict precision is required for the angles shown by arrows B, C, and D. Become. Furthermore, the accuracy of the arrows E and H of the magnetic head 4 is
This is related to the accuracy of the wrapping angles of arrows B and C. In other words, since the position of the magnetic tape 3 away from the magnetic head 4 is determined by the positioning of the cassette, changing the position of the magnetic head 4 changes the relative positional relationship with the magnetic tape 3. I will let you do it. That is, due to changes in the lateral direction of the magnetic head 4 (arrow E) and changes in the amount of protrusion (arrow H),
The winding angle (arrows B and C) of the magnetic tape 3 with respect to the magnetic head 4 also changes slightly, and this affects the characteristics of short wavelength recording and reproduction.

Furthermore, since the track is narrow, strict precision is required also in the direction of arrow F, and similarly, fluctuations in the magnetic tape 3 itself in the direction of arrow G also pose a problem. Further, since it is a multi-track device, it is necessary to make stable and uniform contact with the magnetic tape 3 in each track of the magnetic head 4, and accuracy in the amount of tilt shown in the direction of arrow I is also required.

Due to the problem of positional accuracy as mentioned above, the conventional method uses a cassette type as shown in Figure 1.
Magnetic recording and reproduction with short wavelengths, narrow tracks, and multi-tracks was much more difficult than with reel-to-reel systems that did not use cassettes. In other words, in addition to variations in the internal and external shape of the cassette, variations in the positioning of the cassette when it is loaded into the device, and variations in the amount of regulation of the running position of the magnetic tape, there are also variations in the positioning, including the accuracy of the magnetic head movement mechanism. Variations in the recording density have created difficulties in high-density recording using cassette tapes.

According to the configuration of the following embodiment, in a magnetic recording and reproducing apparatus in which a magnetic head moves and is inserted into a cassette to perform recording and reproducing, it has been difficult to ensure the positional accuracy of the magnetic tape and the magnetic head in the past. It becomes possible to record and reproduce short wavelengths using narrow tracks and multi-tracks. The winding angle between the head chip 11 and the magnetic tape 14 shown in FIG.
6 and 17, and can be made less susceptible to the positioning accuracy of the cassette and head unit. That is, arrow B in FIG.
Since the wrapping angle shown by C is always regulated to be constant,
Changes in the lateral mounting position (arrow E) and protrusion amount (arrow H) of the magnetic head 4 no longer affect the recording and reproducing characteristics as in the conventional case. Therefore,
The tip radius of the head chip 11 can be made smaller, making it easier to obtain reproduction output than before.

In addition, as shown in FIG.
By tilting the tip forward, a downward position regulating force in the direction of arrow L is generated on the magnetic tape 14 in contact with the head tip, and the magnetic tape 1 is forced into the downward position regulating guide 18 formed integrally with the head tip 11.
By bringing the lower ends of the magnetic tapes 4 into contact with each other, it is possible to keep the position of the magnetic tape 14 in the width direction relative to the head chip 11 constant with high precision. Therefore, the tracking reproducibility during reproduction can be made less susceptible to the width accuracy of the magnetic tape 14 and the positioning accuracy of the cassette and head unit. In other words, since the running position of the tape in the width direction indicated by arrow G in FIG. These changes no longer affect tracking reproducibility as they did in the past. Of course, in this embodiment, the tilt amount (arrow I) is set in advance, at least the amount that applies the downward position regulating force to the magnetic tape 14 as described above, and the change here refers to variations in the set amount and This refers to changes in the amount of tilt when the head unit approaches. Therefore, since the tracking characteristics are greatly improved compared to the conventional one, it becomes possible to perform narrower track and multi-track magnetic recording and reproducing.

Furthermore, in this embodiment, the assembly accuracy of the head unit, especially the head tip 11 and the wrap angle regulating post 1, is
If the positional relationship between parts 6 and 17 is assembled accurately, there is no need to make the precision of the magnetic head moving mechanism itself, the precision of the cassette tape itself, the relative positional precision of the magnetic head and magnetic tape, etc. any more stringent than before, and the manufacturing process will be easier. It is possible to greatly improve productivity and reliability. Furthermore, during maintenance and replacement, it is only necessary to replace each head unit, and no special alignment work is required, making it possible to reliably bring out high performance with easy work.

As described above, according to the present invention, the winding angle regulating means for regulating the winding angle of the magnetic tape with respect to the magnetic head, and the tape position regulating means for regulating the position of one end of the magnetic tape in the width direction are attached to the magnetic head. The winding angle regulating means and the tape position regulating means are inserted into the opening of the tape cassette together with the magnetic head to perform recording and reproduction. The wrapping angle of the magnetic tape around the magnetic head is controlled by the wrapping angle regulating means, regardless of the installation condition such as height, the positional accuracy of the cassette tape installation, or the variation in relative positional accuracy when the magnetic head and magnetic tape contact each other. It can always be regulated to be constant, and therefore the tip radius of the magnetic head can be made small, spacing loss can be reduced, and reproduction output of short wavelength signals recorded at high density can be easily extracted. Furthermore, by integrally providing a tape position regulating means near the magnetic head, the position of the tape relative to the magnetic head can be kept constant regardless of the other mounting accuracy mentioned above, and tracking characteristics are greatly improved. It is possible to use multi-tracks, each track can be made narrower, and the density of information can be increased in the tape width direction as well. Also, during manufacturing, if only the magnetic head, wrapping angle regulating means, and tape position regulating means are assembled with high precision and this is used as a head unit, the accuracy of other parts does not need to be as strict as before. This invention makes it possible to easily achieve high-density recording using cassette tapes with increased reliability.This invention contributes to the realization of magnetic recording and reproducing devices that can perform high-density recording using narrow track multi-tracks, such as fixed head type PCM recording and reproducing devices. This will make a major contribution.
