Abstract

This paper deals with the security of information storage media in the form of compact discs as a storage medium for internal confidential information stored and stored in military, education, science, and academic institutions.

In preparing and storing a variety of information through a computer, a compact disc having good storage and high information storage density is used as a main information storage medium. These data storage media are easy to carry and are a means of being activated by the development of various recording methods and devices such as CDs and DVDs and storage capacity ranging from 650MB to several gigabytes, but the various information can be easily stored and leaked to the outside. The disadvantage is that it is possible.

In order to remedy these shortcomings, various printing markings, magnetic markings, RF markings, etc. are used on the surface of the disc, but these methods are also exposed to the surface, and the exposed markings are removed or discarded. By cutting off the broken line, it is not read by the reader at the entrance and is stolen.

The present invention forms a groove having a constant depth in the data unrecorded area near the center hole for central CD holding, and the recognition means by the RF method, the recognition means by the MM (Micro Magnetic) method, or the IC chip. By inserting and fixing the same electromagnetic wave sensing and modulating means in the form of a thin plate and sealing it with a separate cover, a security method was developed to prevent the separation or damage of the security means.

Description

Optical data storage device containing security sensing device

The present invention relates to an optical medium information storage device in which a security device using an optical medium provided with a security device prevented tampering is installed.

As a high density storage device using an optical medium such as a laser beam, various optical storage devices such as a compact disc or a digital video disc are provided. Unlike conventional floppy disks, these storage devices store a large amount of information ranging from 600MB up to several gigabytes, and the stored information is not only resistant to temperature and humidity, but also by magnetic field contact, which is the weakest magnetic storage device. There is almost no data corruption, and it is currently the most popular storage device. Furthermore, due to the generalization of the devices in which these storage devices are not simply reading, but also reading and writing at the same time, research records and data of various research institutes, various confidential documents and information of national defense agencies, and corporate information are stored on the computer. After working, they are stored in these optical disk storage devices for permanent storage or transport.

Such an optical disk storage device has a weak point that it can be easily carried once, and in particular, it can read and write at the same time, so that the information accumulated by the various efforts of the above research institutes or companies can be copied in a short time and leaked to outside have.

In order to eliminate this weakness, a means such as bar code, RF modulating means, magnetic signal generating means is attached to the surface of the optical disc, and the signal or magnetic signal generated from these means or the frequency of the frequency generated from the door is attached to the door. Means for detecting and emitting an alarm sound or blocking the door when the external disk of the unsecured optical disc is taken out is widely used. Such a device cannot pass through such a security device if the security means are securely installed on the surface of the optical disc. However, if these means attached to the surface are simply removed using a simple peeling device or even a stationery knife, The problem is that it is possible. In addition to these devices, there are many methods that can be thoroughly secured using expensive equipment, but installation and operation costs are expensive, so it is not practical for general companies or research institutes to use universally unless it is a special place.

The present invention proposes to remedy the above-mentioned disadvantages, and uses an inexpensive security means by frequency modulation or magnetic field modulation, which has been widely used in the past, but uses an optical medium storage device that suppresses any damage of the installed modulation devices. To provide.

The present invention can easily install a storage device such as a blank CD produced as a ready-made product without the installation of a separate facility and equipment for producing such an optical medium storage device or a security device to exhibit the desired security function. It is to provide an optical media storage device that can be easily added security features that can be.

DESCRIPTION OF SYMBOLS 1 Central fixing hole 5: Holder part 10: Security part insertion part 15: Cover 11: Vertical part 12: Adhesive layer A: Security signal detection means 21: Extension part 24: Insertion guide protrusion 25: Insertion hole

The present invention forms a security means inserting part by cutting the data non-recording part of a certain width from a central fixing hole of an optical disk having a thin plate structure of a certain shape to a certain depth, and has a width and a depth corresponding to the security means inserting part. By fixing the security signal detection means such as RF modulation means through, and then to secure the cover and the optical disk with an adhesive to obtain an optical disk with a built-in security means.

Specific embodiments of the present invention will be described with reference to the accompanying drawings.

A representative embodiment of the present invention is shown in cross section in FIG. 1, FIG. 2 shows a plan view thereof, FIG. 3 is a cross sectional view of another embodiment, FIG. 4 is a cross sectional view thereof, and FIG. 5 shows a fixing hole. An example of forming an insertion guide protrusion separately is shown, and FIGS. 6 and 7 are a cross-sectional view and a plan view of an optical disk provided with a conventional security means.

The present invention cuts the holder portion 5, which has no data record formed at a constant width, from the central fixing hole 1 of the optical disk having a thin plate structure to a certain depth except for the reinforcement portion 1a, thereby inserting the security means insertion portion 10. ),

The cover 15 inserted into the security means inserting portion to fill the security means inserting portion is integrated by the adhesive layer 12 formed on the vertical portion 11 of the security means inserting portion 10, and the cover 15 is integrated into the cover 15. It relates to an optical disk configured to secure the security signal detection means (A).

In the present invention, the cover 15 is formed in a symmetrical structure having the same width and height as the security insert 10 as shown in FIGS. It is also possible to suppress external exposure of (A), but in the case where the central holder portion 5 may be weakened, a cover having a reinforcing function may be used as shown in FIGS. 3 and 4 as another embodiment. Can be.

In the present invention, the reinforcing part 1a installed near the central fixing hole has a fixed hole around when cutting to the central fixing hole, and the holding state is unstable, thus preventing the disadvantages of data reading and writing errors caused by various vibrations during high-speed rotation. It is for.

Specifically, as shown in FIGS. 3 and 4, an extension 21 is formed at the side end of the cover to form a separate adhesive layer on the bottom of the extension, or an adhesive layer is also formed on the vertical portion 11 so that the cover and the security insert are integrated. To be The above structure provides a stable structure by exerting a reinforcing function by increasing the height of the holder itself by the expansion function of the expansion part 21 in addition to the function of the simple cover. This configuration can be applied when the reinforcing part is not installed around the central fixed hole, and in this case, the same type of reinforcing part can be formed as shown in FIG. 1 to ensure stable operation.

In this paper, the security signal detection means (A) can be a signal modulation means such as RF modulation or magnetic field modulation, which is widely used in the past, and it is possible to use a printed material which can generate magnetic field materials or other electric magnetic timely signals to the pigment and adhesive.
