Portable Data Storage Device

The present invention relates to a battery-operated portable data storage device, and more particularly, a small hard disk can be used to back up data stored in various types of media used in a portable device and data stored in a CD-ROM. It relates to a portable data storage device that can increase the efficiency of use.

BACKGROUND With the development of digital technology, portable devices capable of storing still images, moving pictures, or audio signals as digital signals are becoming popular. Such devices are used, for example, digital camcorders, digital cameras, MP3P, digital recorders, etc., and most of them are equipped with a storage medium (storage medium) applying a memory device. Such media are used in the form of thin cards that are easily removable such as MMC (Multi Media Card), SMC, DS, Compact Flash (CF), MS (Memory Stick) and MD. The backup method of data stored in each media is performed using a USB or parallel interface, and a PC or notebook computer is usually used to back up data.

1 is an exemplary view showing a state for backing up data from a portable device such as a digital camcorder, a digital camera, an MP3P, or a digital recorder. In the figure, the portable device has taken the digital camera 1 as an example, and the backup device has taken the personal computer 9 as an example. The backup device may also be configured using a notebook computer.

Digital data generated during operation of the portable device is stored in the media (3) embedded in the portable device, and the media (3) is separated from the portable device, and then backed up and stored in the hard disk built into the PC or notebook computer. . The transmission device 5 used for backup is provided with a slot into which the media 3 can be inserted, and the other end is connected to a parallel port or a USB port through a PC and a cable 7.

Most transmission devices transmit data stored in the media 3 using control commands of the PC 9 or the notebook computer while being connected to the PC 9 or the notebook computer. The transmission device is dedicated to the media. Control commands for transferring data from the media are installed in advance in the form of a program on the PC 9 or a notebook computer.

FIG. 2 is an enlarged view of a connection state between the transmission device 5 and the computer 9 of FIG. 1, wherein the transmission device 5 is provided with a slot for attaching and detaching the media 3 storing data. Insert the media 3 separated from (1). The other end of the transmission device 5 is connected by a cable 7, and a connector 9a for connecting with a USB port or parallel port provided in a conventional PC 9 or a notebook computer is connected.

After the connection via the cable (7) is completed, the user can use the program installed on the PC (9) or notebook computer to display the digital data stored in the media (3) on the hard disk (not shown) of the PC (9) or notebook computer. To send.

However, such data transmission has various inconveniences. In other words, since the usable capacity of the media 3 is limited to 8Mb, 16Mb, 32Mb, 64Mb, etc., the media 3 cannot be used when the rated capacity of the media 3 is used up. You should backup it and use it again.

Of course, it is possible to prepare a large number of media in advance and replace it with unsaved media to continue using it, but it is difficult to prepare sufficient capacity because the price of the media 3 is high. In addition, unlike still images, moving pictures require a large amount of storage, making media preparation difficult.

Moreover, PCs are not portable, and even notebook computers developed for portable use have been difficult to use as effective backup devices due to problems such as portability and power supply. Therefore, data stored in the portable digital device can be temporarily backed up, and a portable storage device is required.

The present invention is devised to solve the above problems, and an object thereof is to provide a portable data storage device that can improve the use efficiency of a portable device by temporarily backing up the digital data stored in the media and clearing the media.

Another object of the present invention is to provide a portable data storage device capable of backing up and storing a large amount of data files without purchasing expensive media storage media by transmitting data to various media storage media.

As illustrated, media slots 142 and 144 are formed on one surface of the data storage device 10 to accommodate various types of media. The media slots 142 and 144 may store media currently used and read contents stored in the media. It is also apparent that additional devices capable of recording data can be added if necessary.

After the media 3 is separated from the portable device, it is inserted into a suitable slot among the media slots 142 and 144 provided on the surface of the data storage device 10. After inserting the media 3, the user presses the function input buttons 222 and 224 to input a specific function command. The operation state of the data storage device 10 is displayed on the LCD panel 202 and the operation menu is displayed, so that the user can input necessary functions.

In addition, an interface port 162 and a connection port 262 are formed on the side of the case 28, respectively. The interface port 162 is a port for receiving data from a CD-ROM drive (not shown) and may be configured using a parallel port that is commonly used. In addition, the connection port 262 is a port for data transmission with a PC or a notebook computer, and may be a USB port, a parallel port, or a FireWire (IEEE1394) port, and wireless transmission for a wireless transmission method (for example, Bluetooth). It can be a port.

A block circuit diagram of the data storage device 10 as described above is shown in FIG. As shown in the drawing, the hard disk 12 for recording / reading data can be read and connected to a media detachably mounted on a portable device and storing digital data generated by the portable device.

The hard disk 12 has a large storage capacity, for example, it is preferably configured using a small hard disk used in a notebook. This has the advantage of constituting the data storage device 10 of the present invention at low cost, and also has the advantage of easy handling.

The media interface unit 12 can accommodate various types of media, and is for reading out data stored in the media from the media 3. The media interface unit 12 is flexible to read not only various media currently used but also media of other standards using memory devices. Since the data stored in the actual media are all digital files, knowing the transmission structure of each media can read the correct data. The read data is input to the control unit 18 and processed.

In addition, the media interface unit 12 may be manufactured in a module form. In other words, instead of having a slot for each media (refer to FIG. 3, two media slots 142 and 144 are mounted), a space for storing only one slot is formed, and It is configured by replacing and installing a module having an interface port suitable for media. This configuration has the advantage that the volume of the data storage device 10 can be miniaturized.

The CD-ROM interface unit 16 reads data stored in the CD-ROM from the CD-ROM drive and has a parallel interface or a USB interface.

The controller 18 controls the data storage device 10 by reading necessary data from a ROM / RAM in which a program and control data for controlling the operation of the data storage device 10 of the present invention are stored. The control unit 18 can be configured using a microprocessor (one chip microcomputer). When the media 3 is inserted into the media interface unit 12, the controller 18 determines the configuration state of the media 3, reads out data accordingly, and stores the data in the hard disk 12.

In addition, when a command for transmitting data stored in the built-in hard disk 12 is input from the PC 9, the corresponding data is transmitted. A data transmission interface unit 26 including a connection port 262 is used for transmission. The detailed operating state of the control unit 18 will be described later with reference to the flowchart of FIG. 5.

The display unit 20 is for displaying a state during operation of the data storage device 10, and displays specific characters or figures on the LCD panel 202 for display in accordance with a signal output from the controller 18. The user checks the contents output through the display unit 20 and inputs a necessary command. The display unit 20 includes a panel driver (drive) for driving the LCD panel.

The battery 24 is for supplying power required for the operation of the data storage device 10 of the present invention, and uses a nickel-cadmium-based or alkaline-based battery to simplify portability. Of course, when using the data storage device 10 of the present invention indoors may be further provided with a power supply jack to supply DC power without using the battery 24.

Referring to Figure 5 describes the operating state of the portable data storage device 10 of the present invention as follows.

The user stores digital data generated in the media while using a portable device (eg, digital camcorder, digital camera, MP3P, digital recorder, etc.) for the purpose. When storage is complete or the capacity limit is reached, the user detaches the media from the portable device and inserts it into the media slot.

In the data storage device 10, when the media is inserted into the media slot, the data format is checked and the data format is checked. Wait for input of the command after confirming the data format. When a data transmission command is input in the standby state, data stored in the media is transmitted to the data storage device 10. The transferred data is stored on the hard disk. When the data transfer is completed, the data transfer process is terminated by clearing the data stored in the media.

In the present invention, the operation of transmitting data to the computer 9 is also performed. This is performed by the controller 18 recognizing this command when a data transfer command is input from the computer 9. In fact, it is preferable that the data transfer is made up of an optional menu such as media transfer or computer transfer, so that the user can select it at the time of operating the data storage device 10.

If a data transfer command is transmitted from the computer 9 and a directory for storing data is specified, the data file is transferred. When data is transferred from the data storage device 10 to the computer 9, a menu is configured to collectively transfer all the files stored in the hard disk 12 or to transfer only files selected by the user.

After the transmission of the data is completed, after confirming whether to clear the data stored in the hard disk 12 of the data storage device 10, and if a clear command is input, the file is deleted. If no clear command is input, the operation is terminated without deleting the file stored in the hard disk 12.

As such, according to the present invention, by using a small hard disk, data stored in various types of media used in the portable device and data stored in the CD-ROM can be backed up, thereby increasing the use efficiency of the portable device. By transferring the data, a large data file can be backed up and stored without purchasing an expensive media storage medium.
