Description

disc signal destroyer

technical field

The invention relates to an optical disc signal destroyer, which can destroy the optical disc signal by grinding and prevent the data leakage of the optical disc.

Background technique

According to general CD, VCD, DVD and other optical discs, the signal data is transformed into a series of pits and lands of different sizes through embossing technology, and the signal data is stored in the optical disc, and then the content of the optical disc is read by laser discrimination.

When the optical disc is no longer used and it is to be discarded, the important data stored in the optical disc may leak out thereupon. In order to avoid data leakage, when the optical disc is going to be discarded, it is best to destroy the stored signal, so as to prevent the important data stored in the optical disc from being accidentally leaked.

Among the storage areas of the optical disc, there is an area called the directory lead-in area (START LEAD IN, referred to as SLD), which is where the lead-in signal of the data stored in the optical disc is recorded. The position of the directory lead-in area on the optical disc is a circular position with a diameter of about 46mm (that is, a position about 23mm away from the center point of the optical disc). all data for .

Currently, there is no relevant structure or device on the market, which is specially used to destroy the signal in the directory lead-in area of the optical disc, so as to achieve the effect that it cannot read data and thus prevent data leakage.

Contents of the invention

The object of the present invention is to provide an optical disc signal destroyer to solve the above problems.

The object of the present invention is achieved by providing an optical disc signal destroyer, which includes a base and a scraper, the top surface of the base has a groove for holding the optical disc, and the central part of the groove is provided with a There is a vertical through hole; and the scraping body includes a handle portion, a scraping element is laid on the bottom of the handle portion, and a protruding shaft protrudes downward from the center of the bottom of the handle portion and is contained in the seat When operating the scraping body to rotate on the optical disc with the protruding shaft as the axis, the scraping element of the scraping body can scratch and destroy the signal on the directory lead-in area of the optical disc, so that the optical disc The stored data cannot be read, preventing the data leakage of the disc to be discarded.

Detailed ways

The structure, features and effects of the present invention are also described in detail in accordance with the embodiments of the accompanying drawings as follows.

Fig. 1 is an exploded sectional view of the optical disc signal destroyer of the present invention, Fig. 2 is a combined sectional view of the optical disc signal destroyer of the present invention and shows its use state diagram, and Fig. 3 is a transverse view of the handle portion of the scraper body of the optical disc signal destroyer of the present invention cutaway view.

As shown in the figures, the optical disc signal destroyer of the present invention includes a base body 1 and a scraper body 2 .

The above-mentioned base 1 is provided with a groove 11 on its top surface, which is suitable for holding a disc 3 to be discarded. The central part of the groove is provided with a vertical through hole 12, and the aperture of the through hole is about the same as the center of the disc 3. Hole 31 aperture, and this through hole can be used as the limit guide hole when scraping body 2 following protruding shafts rotates. In addition, the groove 11 is laid with an anti-slip bearing pad 13, which is made of a wet material such as rubber material or the same material as the following scraping element to make a plane bearing pad with a wet anti-skid effect, so that it is wet with the optical disc 3 contact to prevent the disc from slipping when the disc is damaged as described below.

The above-mentioned scraping body 2 includes a handle part 21 , a scraping element 22 laid on the bottom of the handle part, and a protruding shaft 23 protruding downward from the center of the bottom of the handle part. The area covered by the scraping element 22 is to cover the directory lead-in area 32 of the optical disc, and the scraping element is any element that can scratch and destroy the optical disc signal, which is usually a hard and wear-resistant solid element, such as a sand body (sandpaper) , metal particles or wires, etc.

When the signal on the optical disc is to be destroyed in order to prevent the data leakage of the optical disc 3, the anti-skid bearing pad 13 is placed in the groove 11 of the base body 1 with the printing surface (signal recording surface) of the optical disc facing upwards. At this time, the central hole 32 of the optical disk is aligned with the through hole 12 of the base body 1; then the scraping body 2 is contained in the through hole 12 after passing through the central hole 32 with its protruding shaft 23, the The scraping element 22 of the scraping body straddles the signal recording surface of the optical disc 3 . When holding the handle portion 11 of the scraping body 2 and operating the scraping body to rotate, the scraping body can be rotated with its protruding shaft 23 contained in the through hole 12 as an axis. While rotating, the scraping body will scratch and destroy the signal of the CD 3 directory lead-in area with the scraping element 22 on its bottom surface, so that the data on the CD cannot be read, reaching its effect of preventing data from leaking.

Moreover, in order to facilitate the rotating operation of the scraping body 2 and prevent sliding during the rotating operation, an anti-slip structure is provided on the outer periphery of the handle portion 21 of the scraping body 2 , for example, a concave-convex surface 24 is provided on the outer periphery of the handle portion.

To sum up, the present invention provides an optical disc signal destroyer, which can easily destroy the signal of the directory lead-in area on the optical disc, and by destroying the signal of the directory lead-in area, the data cannot be read and the data leakage is prevented. Effect.
