Abstract: A disc cartridge that can simultaneously adjust a plurality of functional holes indicating whether or not the disc cartridge for receiving a double-sided disc has an opened or closed experience, and a disc driving apparatus for sensing the open and close state of the functional holes. In the disc cartridge, a body is provided with at least one of opened or closed experience confirming hole indicating whether or not the cartridge has an opened or closed experience. An opening and closing member allows a confirmation of an opened or closed state with respect to each face of the disc by an opening or closing of any one of the opened or closed experience confirming holes. Accordingly, the opened or closed state of the plurality of opened or closed experience confirming holes corresponding to the double-sided disc can be simultaneously adjusted, so that a user's convenience can be improved.

Abstract: A disc cartridge that can provide various driving modes for a disc received within the cartridge and allows a user to select the driving modes efficiently. A disc recording/reproducing method and apparatus employing the disc cartridge is disclosed. In the disc cartridge, a recording prohibition mode, a verification preceding recording mode and a direct recording mode are used. A mode selector can select each mode. The disc cartridge can provide various driving modes at a user's request and permits a user to select the driving modes efficiently by a single selector.

Abstract: A disc cartridge that is adapted to receive a small-size optical disc and is compatible with a large-size disc cartridge. In the disc cartridge, first and second shutters open and close an opening. A connector links the first shutters to the second shutters as any one of the first and second shutters is driven.

Abstract: The disc protection casing includes a casing body and a disk holder. The casing body has a receiving space therein and an access port formed in a first side of the casing body. The disk holder is insertable into an interior of the casing body via the access port, and one of the disk holder and the first side of the casing body is structured such that the disk holder is prevented from being incorrectly inserted into the casing body.

Abstract: A disc cartridge adapter that is capable of driving a different size of disc cartridges with the same disc driver. In the adapter, a driving power transfer device absorbs a difference in a shutter travel range having a different size from each other to drive shutters of a small-scale disc cartridge. A body is provided with a receiving space for receiving the small-scale cartridge. Accordingly, the small-scale cartridge can be driven with a disc driver for driving a large-scale cartridge.

Abstract: A toy having a detachable central processing unit is comprised of a central processing unit with a built-in growth algorithm for having the toy grow, a driving unit for exhibiting action according to growth or outputting an audio information and a link unit for linking the central processing unit and the driving unit. Therefore, in case of using just the central processing unit, the toy with which the toy can grow or to which application programs are installed using the cyber character so as to utilize as a Personal Digital Assistant (PDA), mobile phone and a computer for home-use. Also, in case the toy is combined with the central processing unit, it can perform more improved actions thus to give a variety of learning chances and attract a variety of interest.

Abstract: A toy learning apparatus using a cyber community and a method thereof comprising a cyber community having a cyber character which grows by learning in online, and a toy which grows by receiving experience of the cyber character or experience of a user's learning can increase the interest of the user, promote the sale of the toy and supply the program update of the toy, contents and various kinds of information smoothly by connecting the actual toy and the cyber character which acts in the cyber community.

Abstract: In an apparatus and a method for operating toys through a computer communication, an apparatus for operating toys through a computer communication comprises a communication server supplying message information through a computer communication in a network, an operation device interpreting the message information inputted from the communication servers, and a toy being inputted the message information from the operation device and performing a certain motion or outputting character information/audio information/image information corresponded to the inputted message information, accordingly a user can perform a computer communication with reality and have better interaction between users.

Abstract: A system for programming an interactive learning device, such as electronic toy, using a web server includes a first processing unit having a web server for providing a control module used for remote processing, a second processing unit linked to the first processor through the communication medium to exchange data with the first processor, an interactive device, such as a robot toy pet, having at least a processor and a memory and adapted to communicate with the first processing unit. The interactive device includes a sensor for collecting data and formulating a learned module. The interactive device receives the control module from the first processing unit and sends the learned module. The control module is updated with more advanced function to be performed by the interactive toy in response to the content of the learned module.

Abstract: A learning/growing system of a toy using real living goods to solve problems of conventional art, that is, that the method of conventional art is too simple and related to real life little, whereby the growing of the toy is monotonous and the user can not be interested in the toy continuously, comprises a learning/growing toy expressing desires for eating, learning, and playing at a certain time point, and grown intellectually and physically by being inputted products and goods information corresponding to satisfaction of the desires; a personal computer for downloading the goods information for satisfying the desires of the toy and inputting the information into the learning/growing toy; and a web server recognizing the desire generations of the toy and including advertising banners for various products of many companies and detailed information according to the banners.
