Description

Portable data storage and playback device

technical field

The invention relates to a storage and playback device, and particularly relates to a portable data storage and playback device.

Background technique

In recent years, due to the rapid development of information products, data storage and transmission technology has become one of the hot research topics. At the same time, the types of storage media have also increased rapidly. Among them, flash memory cards have a wide range of applications, and general information appliances Supplies such as digital cameras, notebook computers, MP3 players, personal digital assistants (PDAs), and various portable electronic products are almost available, making the flash memory market always in short supply, and the prices remain high.

When the memory card of the electronic product has no space, the electronic product cannot store the desired data. At this time, the desired data in the memory card must be dumped or backed up before it can be used to store new data. For example, when the memory card of a digital camera is full of digital images, the memory card must be taken out, and a computer device with a reading device is used for data backup. The reading device can generally be, for example, a card reader or a PCMCIA (personal computer memory card association) card, and can be connected to a computer device through a common Universal Serial Bus (USB) interface.

However, when the user cannot immediately obtain the computer device for real-time backup, such as when traveling abroad, he needs to purchase several memory cards to store the required data. However, the price of the memory card is very high. Therefore, the applicant has filed an application for a patent for invention of No. 091116547 "portable data backup device" on July 25, 2002 to solve the above-mentioned memory card data backup. The problem. The portable data backup device disclosed in the above application includes a card reader for reading digital data of a memory card; an input unit for generating a control signal; a backup unit for storing data; And a control unit, after receiving the control signal, causes the card reader to read the digital data of the memory card and store it in the backup unit. In addition, a playback unit can also be set in the portable data backup device to play the digital data in the memory card and the backup unit. In this way, the data read from the memory card can be backed up to the backup unit through the card reader. In addition, the portable data backup device can also be connected to an external computer device through the USB interface, so that the computer device can read or play the data in the memory card or the backup unit.

However, although the portable data backup device disclosed in the above application can solve the problem of memory card data backup, its data source is still limited to reading the memory card by the card reader on the portable data backup device. In other words, although the portable data backup device disclosed in the above application has a USB interface, it can only be used as an interface to connect with an external computer device, and cannot be used as a host to directly connect with other computer-related peripheral devices. connection for data transfer. This then greatly limits the purposes of the portable data backup device.
