Multi-type portable digital data preservation adapter {PORTABLE ALL-IN-ONE DIGITAL DATA STORAGE CONVERTER}

The present invention relates to a multi-type portable digital data preservation adapter, and more particularly, to an adapter capable of transferring digital data between various other storage media as an element of a computer, and performing exchange preservation of digital data at will.

With the rapid development of information science and technology, the transmission speed and storage capacity of digital data are greatly increased, whereby a large amount of digital data is stored and read out by a computer and used as a storage medium for the storage data. There are devices such as memory cards, portable disks, recording pens, PDAs, personal video recorders (PVRs), digital cameras, USB CD-ROMs, A / V decoders, USB MP3 players, and card readers. In a conventional method for transmitting the data, these information facilities are connected to a computer using a cable, and further, digital data are transmitted, stored or read from each other via a computer. This approach needs to be computer-borne and requires a computer for transmission. In practice, however, it is not always necessary to have a computer, and some computers cannot be combined. Therefore, in some cases, inconveniences arise when one wants to use the computer.

An object of the present invention is to provide a kind of multi-type portable digital data preservation adapter. It is assumed that the device is an apparatus capable of exchanging digital data among various other storage media without requiring media by a computer, and achieving a function of storing digital data anytime and anywhere.
