Description
3t;~
This invention relates to a jacket for rotatable magnetic recording media and more particularly to a protective structure for the jacket which can prevent dust from entering the jacket.
Rotatable magnetic sheets (generally known as floppy discs) are widely used as meclia for magnetic recording and reproducing in recent years. These rotatable magnetic sheets are usually sheathed in a package (referred to as a jacket hereinafter) provided with internal liners made of non-woven fabric. The jacket has an opening at the center thereof for rotating the magnetic sheet, an opening for contacting the rotatable magnetic sheet with a magnetic head and an opening for displaying sectors. Dust in the air tends to enter the jacket through these openings to contaminate the surface of the magnetic sheet, and cause errors.
Such a jacket is us,ually placed in an envelope for protecting it mainly ~rom such dust. However, as such an envelope covers only two thirds or three fourths of the surface of the jacket and is not closel~ attached to the opening of the jacket, dust in the air cannot be fully prevented from entering the jacket within the envelope.
Moreover, the jacket is taken out from the envelope when a user wishes to use the rotatable magnetic sheet therein, and the user tends to throw away the envelope. The openings of a jacket are often exposed to the air when such sheet is stored for a long time.
The material of such an envelope was mainly made of : .
- , ; :i, . ;:
, .".
~2~ 7 natural paper in the prior art, but recently they are often made of synthetic sheet such as polyethylene (e.g. TYVEK (trade mark) Manufactured by DuPont).
When we consider costwise a product comprising a rotatable magnetic sheet, a jacket and a protective envelope, the cost of the envelope is by no means negligible as it is not quite effective in preventing entry of dust.
This invention aims to provide a protective structure for the jackets of rotatable recording media which can almost completely prevent dust in the air from entering the jackets and yet is low in cost.
The protective structure for rotatable recording media jackets according to this invention is characterized in that a protective sheet which is applied with adhesive on one surface thereof covers at least an opening of the jacket for driving the magnetic recording medium therein and an opening for contacting the magnetic recording media with a magnetic head out of the aforementioned various openings on the jackets. As these openings are formed in both sides of a jacket, it is desirable for the structure to cover them from both sldes. Two notches are provided near the opening for contacting the media with the magnetic head.
They are preferably covered with the protective structure together with the opening.
The protective sheet may be in any form so long as it can effectively cover the openings of the jacket.
The openings of a jacket are covered with such a protective sheet to prevent cLust from entering them. When

FIGURE 3 is a developed view of the protective sheet. The protective sheet 1 is substantially rectangular with semi-circular ends. The rounded end portions are for covering the opening 3 at the center of the jacket 2 for driving the rotatable magnetic sheet. A folding line 6 exists at the center of the protective sheet 1. The sheet 1 is folded on the line 6 symmetrically to cover the opening in the jacket from both sides in a manner shown in FIGURE 1. The protective sheet 1 is made of synthetic paper and is applied with adhesive on the surface which contacts with the jacket for snug attachment.
; If adhesive is applied only on the peripheral portion 8 of the sheet 1 as shown by a broken line in FIGURE 3, the rotatable magnetic sheet which is exposed through the openings on the jacket 2 will be free of such adhesive.
FIGURES 4 and 5 show another embodiment of this invention. The protective sheet according to this embodiment is shaped like a dumbbell or two circles connected by a rectangle.
The circular portions are for covering the opening 3 for driving the rotatable magnetic sheet and the opening 5 for displaying sectors while the rectangular portion together with the circular portions are to cover the opening 4 for contacting the rotatable magnetic sheet with the magnetic head.

In this embodiment the protective sheet 1 is formed in two sectors and is to be folded symmetrically at the folding line 6 to cover the opening 3 for driving the rotatable magnetic sheet, the opening 4 for contacting the magnetic sheet with the magnetic head and the opening 5 for displaying sectors. This protective sheet does not cover openings of notches 7 on the jacket 2.
This invention provides a protective structure which covers a jacket with a protective sheet. When a rotatable magnetic recording media in the jacket is used for recording or reproducing, the protective jacket is peeled off from the jacket and then the jacket is inserted in a magnetic disc unit or the like.
