Embodiment approach 1

[0036] figure 1 It is a figure which shows the plugging sealing material for recording apparatuses concerning Embodiment 1 of this invention.

[0037] The hole plugging seal 10 for a recording device according to Embodiment 1 has a function of blocking a through-hole provided in a housing of the recording device.

[0038] like figure 1 As shown in (a), the plugging seal 10 for a recording device is attached to the base paper 1 before use. This recording device plugging seal 10 has an adhering portion 2 on which a detachable adhesive layer is formed. In addition, a non-adhesive folding margin 3 is formed at one end of the sealing member 10, and a crease 7 is formed at the boundary between the non-adhesive folding margin 3 and the sticking portion 2. The marks 7 are grooves that are concave on a straight line. Here, the depth of the concave groove is preferably formed in a range of 0.1 μm to 58.0 μm. If it is less than 0.1 μm, it will not bend upward from the backing paper....

Embodiment approach 2

[0051] image 3 It is a perspective view showing a method of manufacturing a plugging seal for a recording device according to Embodiment 2 of the present invention.

[0052] In the hole plugging material for a recording device according to Embodiment 2 of the present invention, an adhesive layer is formed with a silicone-based adhesive on one side of a long sheet made of a polyester film. Then, a film for removing adhesiveness is attached to the site where the folding margin is to be formed.

[0053] Then, the above-mentioned long sheet was bonded to the long base paper in which the high-quality paper, the filling layer, and the release layer were laminated. On the surface of the side on which the recording device plugging seal is to be formed, the sheet produced in this way is partially punched using a predetermined clickercutter to form figure 1 A plugging seal for a recording device having a shape as shown is shown. Then, the sealing material of unnecessary portions oth...

Embodiment 1

[0057] A plurality of plugging seals for recording devices described in Embodiment 1 above were manufactured. The hole plugging material for a recording device is formed of an affixed portion in which an adhesive layer made of a silicone-based adhesive is laminated on a polyester film, and a folded margin portion that does not have adhesiveness due to the affixed film. Then, the produced plugging material for recording devices was attached to a base paper of 19 cm x 8 cm in which high-quality paper, a filling layer, and a peeling layer were laminated. The number of recording device plugging seals attached to one base paper is 50 sheets.

[0058] 100 sheets of backing paper to which the recording device plugging seal was attached were produced, all the sheets were stacked, and a 5 mm thick wooden board was placed thereon, and a 5 kg counterweight was further placed. It was left to stand in this state, and the bottom sheet was taken out every 24 hours, and the distance between ...

Abstract

Provided are hole-blocking seals for a recording device that allow for quick sealing of multiple holes in a hard disk drive and that can be quickly peeled off after information has been recorded. The bending shape of a portion of each hole-blocking seal for a recording device is preserved even when multiple sheets are stacked. Each hole-blocking seal (10) for a recording device comprises a bonding part (2) with a portion having an adhesive layer thereon that allows for detachable attaching thereof for blocking a through hole which is disposed on a casing body of a recording device. A non-stick fold tab (3) is formed on one end part of the seal. A fold line (7) is formed on the boundary between the non-stick fold tab (3) and the bonding part (2) by a recessed groove.

Description

technical field [0001] The present invention relates to a detachable hole blocking seal for a recording device for blocking a through hole provided in a housing of a recording device (hard disk drive). In particular, by forming a folding margin that does not have an adhesive layer at the end of the hole plugging material, it is possible to speed up the attachment and detachment of the hole plugging material. Background technique [0002] In recent years, recording devices (HDDs) rotate magnetic disks at high speeds in order to meet the required characteristics of large capacity and high-speed processing. Therefore, it is clarified that because the friction value and / or resistance value inside the HDD becomes larger, or the airflow caused by the vibration of the disk will affect the positioning control of the disk and the read head, the more the disk speed increases, the more It is not easy to achieve the effects of capacity and / or high-speed processing of HDD. In addition,...
