Abstract

PURPOSE:To suppress the vibration of a magnetic tape at the time of traveling and to prevent azimuth loss by arranging two plate-like blocks in parallel through plural struts and guiding the magnetic tape on the opposed plane of the two blocks. CONSTITUTION:Grooves 9, 9' are formed on the upper surface of a plate-like block 8 fixed on the upper surface of a base 1 and a magnetic head 4 is fixed on spacers 5 fitted to the grooves 9, 9'. Six struts 10 are planted into the block 8 and holes 12 of a plate-like block 11 are inserted and fixed into/on the struts 10 on four corners out of these struts 10 to keep the blocks 8, 11 in parallel. The magnetic tape 7 is guided between the upper surface of the plate-like block 8 and the lower surface of the block 11. Consequently, the inclination of the magnetic tape 7 to the magnetic head 4 and waving are removed and stable traveling is attained without getting out order of azimuth according to the residual of the tape on a reel.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a magnetic recording and reproducing apparatus for recording and reproducing by running a magnetic tape.

A conventional device of this type will be explained with reference to FIG. 1, without focusing on the configuration of the conventional example and its problems. In FIG. 1, reference numeral 1 denotes a substrate, and a head mounting plate 3 is fixed to the substrate 1 via a fixing post 2. As shown in FIG. 4 is a magnetic head fixed to the head mounting plate 3 via a spacer 6; 6° 6' is a cylindrical tape guide post located near both sides of the magnetic head 6 and supported by the head mounting plate 3; Flanges for guiding the magnetic tape 7 are formed at the top and bottom.

In FIG. 1, the magnetic tape 7 is guided by two parallel tape guide posts 6.6 and runs in the direction of the arrow.

However, in the conventional device described above, the parallelism of the two tape guide posts (6.6') was poor, and if there was a dimensional difference in the guide width of the tape guide posts (6.6'), the magnetic tape 7 This has the disadvantage that vertical and horizontal waving and meandering occur with respect to the head 4, causing azimuth to go out of order and level fluctuations to occur. Particularly in devices for recording and reproducing digital signals, the above-mentioned tape guide mechanism has an adverse effect on the characteristics.

OBJECTS OF THE INVENTION The present invention solves the above-mentioned conventional drawbacks, and an object thereof is to provide a magnetic recording and reproducing device that can suppress tape vibration during running, obtain smooth tape running, and suppress unmass loss. It is something.

Structure of the Invention The present invention comprises two flat blocks arranged in parallel via a plurality of supports, a groove formed in at least one of the opposing surfaces of the two blocks, and a magnetic head provided in this groove. , the magnetic tape is guided by the elastic material formed on the opposing surfaces of the two blocks or the opposing surface of one block and the opposing surface of the other block, thereby reducing tape vibration during running. The present invention provides a magnetic recording and reproducing device that can suppress the azimuth loss, obtain smooth tape running, and suppress azimuth loss.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below. In FIG. 2, reference numeral 1 denotes a substrate, and a flat block 8 is fixed to the upper surface of this substrate 1. As shown in FIG. A groove 9.9' is formed in the upper surface of this block 8, a spacer 5 is mounted in this groove 9.9', and a magnetic head 4 is fixed to this spacer 6. Six pillars 10 are installed in the block 8.

The holes 12 of the flat block 11 are inserted and fixed into the pillars 1o planted at the four corners of the six pillars 1o, and the blocks 8 and 11 are held in parallel. 13.13'
is a groove formed on the lower surface of the block 11. In this embodiment, the upper surface of the flat block 8 and the flat block 1 are
The magnetic tape 7 is guided by the lower surface of the block 8 and the magnetic head 4, and within the range guided by the blocks 8 and 11, there is no inclination or waving of the magnetic tape 7 with respect to the magnetic head 4, and the azimuth will be out of order depending on the amount of tape remaining on the reel. This eliminates level fluctuations and provides stable running.

FIG. 3 shows a second embodiment of the invention.

In this embodiment, thin elastic members 13 are provided at several places on the lower surface of the block 11 of the embodiment shown in FIG. 2 to absorb movement due to width fluctuations of the magnetic tape, and the effect is almost the same as that of the first embodiment. is obtained.

Effects of the Invention The present invention eliminates tilting and waving of the magnetic tape with respect to the magnetic head over the length of the block by increasing the right angle between the support and the two blocks, preventing the azimuth from going out of order and preventing level fluctuations. This eliminates the problem and enables stable tape running.
