JPS61192015A - Production of head cleaning tape - Google Patents

Abstract

PURPOSE:To reduce the effect of a magnetic head even in case the head is driven repetitively with a magnetic recording/reproducing device, by forming intermittently the films with a material having the cleaning function on the magnetic surface of a magnetic recording medium and therefore eliminating a joint part between a checking tape and a cleaning tape. CONSTITUTION:A coating material is applied intermittently to a checking tape 6 by the up-down movement of a roll 7. The tape 6 contains a magnetic layer and can record and reproduce signals. A roll 8 carries the coating material from a supply part 10 by its revolutions. A knife 9 functions to control the coating material carried on the roll 8 to a fixed amount. Then the tape 6 is driven and at the same time the roll 7 is moved up and down repetitively and synchronously with the drive of the tape 6 to apply the material having a cleaning function to the tape 6 at a fixed interval. Then the tape 6 undergoes the drying and other processes and is slitted finally. Thus a desired cleaning tape 5 is obtained with application of a material having the cleaning function. Thus it is possible to obtain both checking and cleaning functions with a single tape with no joint produced between both tapes.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention is useful for removing foreign matter adhering to the magnetic head and traveling system of a magnetic recording/reproducing device, as well as for recording/reproducing check (
This article relates to a method of manufacturing a y-do cleaning table that has the following functions (hereinafter referred to as "check").

BACKGROUND OF THE INVENTION A head cleaning tape manufactured by a conventional head cleaning tape manufacturing method is, for example, manufactured by Utility Model No. 49-1.
As shown in Publication No. 08003, it had the structure shown in FIG. 3.

That is, cleaning tape 1 and checking tape 2.
are joined together with tin rising tape 3.

This is a method in which two types of tapes, each with different properties, are joined together to be used as one tape.

Problems to be Solved by the Invention However, according to this method, if the spliced portion repeatedly runs over the magnetic head, it is expected that the adhesive material of the tin rising tape will peel off and seep out. In the worst case, recording and reproducing functions may become impossible.

Therefore, the present invention is designed to provide both checking and cleaning functions without having to join them together.

Means for Solving the Problems The technical means of the present invention for solving the above problems is to provide a checking function by intermittently forming a film of a material having a cleaning action on the magnetic surface of a magnetic recording medium. The company manufactures head cleaning tapes with cleaning functions.

Effect of the Invention The present invention uses the method described above to avoid splicing the checking tape and the cleaning tape together using the splicing chive, so there is no risk of damage to the magnetic head and running system due to peeling of the spliced part or seepage of the adhesive from the splicing chive. Eliminated negative effects. It becomes possible to obtain a tape that combines both checking and cleaning functions.

EXAMPLE Hereinafter, an example of the present invention will be described based on the accompanying drawings.

FIGS. 1A and 1S are schematic diagrams showing an embodiment of the method for manufacturing a head cleaning tape of the present invention. In FIGS. 1A and 1S, reference numeral 6 denotes a check tape on which a magnetic layer is already formed and on which signals can be recorded and reproduced.

The checking tape 6 is coated with paint intermittently by the vertical movement of the roll 7. The roll 8 receives paint from the material supply section 10 and conveys the paint by rotation. The knife 9 runs the check tape 6 with a configuration of 0 or more that regulates the amount of paint that has been carried on the surface of the roll 1o, and repeats the vertical movement of the roll T in synchronization with this. A material with a cleaning effect is applied at predetermined intervals.

The check tape 6 coated with an appropriate amount of a material having an intermittent cleaning/greasing effect is dried and other processes, and then slit to finally form the tape shown in FIG. 6 is a cleaning tape coated with a material having a cleaning effect. In this way, it is possible to have both checking and cleaning functions without the need for splicing.

It should be noted that it can be manufactured by coating, vapor deposition, and other treatments using equipment other than those described above, and the same effect can be obtained.

Effects of the Invention In the present invention, since there is no joint between the check tape and the cleaning tape, even when the tape is repeatedly run in a magnetic recording/reproducing device, there is little effect on the magnetic head. Furthermore, it is possible to continuously produce the checking tape and the cleaning/cleaning tape, resulting in the effect that the number of man-hours can be significantly reduced.
