Abstract

The present invention relates to a card recording disk in the form of a card. Unlike a conventional disk, a rectangular disk could not be used without a special device. It aims to use disk stably without damage by making it available.

A feature of the present invention is to use a card type CD disc by cutting a part of the existing 11.5 cm and 8 cm circular discs and attaching a thin card type rectangular plane to the opposite side of the recording surface. Therefore, it is possible to record on the remaining part after cutting from the circular disk, and stably used in the existing CD drive, and because of the rectangular shape added to the opposite side of the recording surface, various types of printing can be used like business cards.

Description

Card Type CD Disk {CARD FORM FOR CD DISC}

The present invention is designed to be used like a business card after storing data on a popular CD disk, and it can be more securely mounted on a CD disk than a conventional product, and a cleaner print on an additional rectangular panel.

The present invention relates to a card recording disk in the form of a card, and the existing card type CD disk is frequently removed when the card is extracted from the CD disk drive, thereby damaging the disk recording surface.

In general, as shown in FIG. 4, the disc drive includes a tray 92 for mounting the disc 11 and a loading base 93 which transfers power to the tray 92 to guide the tray 92 back and forth. ), A turntable 94 for rotating the disk 11 mounted on the tray 92, and a rotation after lifting the disk through the turntable hole 98 of the disk 11 by the turntable 94. A clamping holder (not shown) for supporting the disk 11 thereon, and a pickup module 95 for optical pickup while advancing back and forth the recording surface of the disk 11 rotated by the turntable 94. It is done by Therefore, when reproducing the optical disc 11 such as the CD-ROM drive, the optical disc 11 is reproduced by driving the disc drive attached to the computer.

A card type CD disk which has been modified from the 11.5 centimeters and 8 centimeters of the circular disk 11, which has been used in the past, has been used recently. A protruding border was attached to the recording surface of the CD disk as shown in 31 of 5 to fit the small groove of the CD drive, and the second technique was shown after cutting a 11.5 cm circular disk into a rectangle as shown in FIG. Like 32 of 5, the rubber product is attached to four rectangular corners so that it can be mounted without slipping. However, the present invention is necessary because stable operation is insufficient when the CD drive is driven.

Accordingly, the present invention has been made in consideration of the above-described conventional problems, and an object of the present invention is to provide a card-type disk capable of stably driving a rectangular CD disk in the form of a business card or credit card in a disk drive.

In order to achieve the above object, the present invention can use a method of bonding a rectangular cross section of a thin homogeneous or similar product to the opposite side of the recording surface after cutting the circular CD disk, and also a method of manufacturing a conventional CD disk Using a special chemical treatment to reflect the reflected light between the two circular plastic panels (Fig. 2) using the current recording surface is cut out both sides of the circle shape of Figure 4 and the top (printing surface) is shown in Figure 5 It is characterized in that it can be as shown in D of FIG.

In addition, according to the present invention, it is possible to freely attach a cross-section of the design, such as a triangle, a square, in addition to the rectangular shape can be used to create a unique CD disk.

Other features and advantages of the present invention will become more apparent from the following detailed description of the preferred embodiments based on the accompanying drawings.
