The switch 42 is a jog key, which is soldered on a Printed Circuit Board (PCB), and the signal pin is connected to the power switch controller 44, and the other end of the jog key is exposed through an opening of an external device, and can be manually pressed by a needle, and when the jog key is pressed for a long time, the level state of the signal pin is changed to notify the power switch controller 44 to perform switching management on the hard disk, i.e., the bright disk 50 and the dense disk 60.
The power supply switching controller 44 is responsible for selecting and managing the bright disc 50 and the dense disc 60, and may adopt an ADuC816 type single chip microcomputer, which is a microcontroller with an 8051 core, and is connected to the switch 42 through a General-purpose input/Output interface (GPIO for short), and detects a state change of the switch in real time.

(III) Ming dish
Fig. 3b is a block diagram of the structure of the bright disc according to the preferred embodiment of the present invention, and as shown in fig. 3b, the bright disc 50 is composed of a bright disc controller 52 and a bright disc storage unit 54, and a power supply and reset circuit, wherein the bright disc storage unit 54 may be a Flash array. The transparent disk 50 is actually a solid state disk, a Flash type nonvolatile semiconductor is used as a storage medium, and Flash is simulated as a storage unit organization form of a disk, namely a sector, by the transparent disk controller 52, so that complete compatibility with the disk is realized. The bright disk controller 52 can be connected with 6 flashes in parallel, that is, all signal lines between chips are independent, the first storage unit of each Flash forms a first group, six groups in total, buses between groups are shared, and control signals are independent. If the writing speed of 8MB/s and the reading speed of 10MB/s are taken as the reference, the theoretical maximum writing speed can reach: the theoretical maximum reading speed can be achieved with 6x8 MB/s-48 MB/s: 6x10 MB/s-60 MB/s.
The bright disk controller 52 can manage a plurality of flashes in parallel, simulate a standard disk device, realize SATA and USB interfaces, and realize data transmission with external devices such as a PC. The pseudo-random mapping from the logic address to the flash memory physical address can be realized, the data is stored in a decentralized manner, the data is highly decentralized, and the read-write balance can be controlled: the erasing life of the Flash storage medium is limited, if a certain storage area is always erased, a storage bad block of Flash is caused, so that the life of the hard disk is reduced, and therefore the Flash controller 52 can uniformly manage the whole Flash storage area and perform storage balance control.
The bright disk controller 52 runs a firmware program by using a 32-bit ARM embedded processor to realize storage management of Flash, SATA command analysis, processing of various interrupts, and the like.

The built-in Error Correction Code (ECC) Error correction and hard disk Self-Monitoring Analysis and Reporting Technology (SMART) function and power-down protection function are supported, so that the data security is ensured. The bright disk controller 52 also prolongs the service life of the Flash chip through an equalization algorithm, and has a wide working temperature range, a general level of 0-70 ℃ and a wide temperature level of-40-85 ℃.
(IV) dense disc
Fig. 3c is a block diagram of the structure of the optical disc according to the preferred embodiment of the present invention, and as shown in fig. 3c, the optical disc 60 includes an optical disc controller 62, an optical disc storage area 64, an encryption module 66 and a password detection module 68. In order to prevent illegal access to confidential data in the confidential disc, an encryption module 66 based on AES encryption technology data transformation design is added in the embodiment to ensure the security of the data.
When a user needs to access the data in the compact disc 60, the correct password must first be entered, otherwise the encryption module 66 will be in a protected state and the data will not be accessible through it, meaning that the user will not be able to access the hard disk. The secret 60 is only accessible after authentication by the password detection module 68. The password can be set when the compact disc leaves a factory or can be set by software. When the user obtains access authorization through the encryption card, the hard disk is seen on the external equipment such as a computer, wherein the data is encrypted through an AES encryption algorithm. If the unlocking key is not available, even if the Flash chip of the compact disk 60 is forcibly detached to obtain data, the information involved in the data cannot be obtained.
The input of the password is triggered by continuously changing pulses generated by the keys, so that the detection of password key signals is realized. Password button signal passes through the button and produces, and the button welding is on the PCB board, and signal pin links to each other with the singlechip, and the other end exposes through the external equipment trompil, can press through the needle by hand. When the single chip detects the matched continuous key pulse, a set AES key is generated to the encryption module 66, and the encryption module 66 starts to work after receiving the correct key.

After the system is powered on, the hard disk switching unit judges the state of the hard disk switching switch, and when the hard disk switching switch is in a default state, the hard disk switching unit indicates that an open disk is selected, otherwise, the hard disk switching unit indicates that a closed disk is selected. In addition to the determination according to the switch state, the selection of the open disc or the closed disc can also be determined by receiving the wireless control signal.

Step S408, the open disk executes the hard disk function and monitors the destruction signal.
When the switching unit selects to start the open disk, the open disk becomes an actual working hard disk, and normal reading and writing, installation of a starting operation system and other operations can be carried out on the open disk. The compact disc is in a power-off state at the moment. When the open disc enters a normal working state, the open disc controller monitors the destruction trigger signal at any time, namely the destruction instruction.
Step S410, judging whether a destroying signal exists.
If the bright disc receives the destruction signal, step S412 is executed, otherwise, step S408 is executed.
In step S412, a data destruction function is performed.
When a destroy signal, namely a destroy instruction, is received, the controller immediately starts a data erasing function and erases all data in the bright disc such as Flash. After the erasure is finished, the internal of the clear disc has no data, and the clear disc is in an unformatted initial state and can be used as a new disc. The flow is ended.
Step S414, starting the compact disc.
The hard disk switching unit controls the power supply and the reset of the compact disk to be switched on, and communicates the SATA signal of the compact disk to the SATA interface of the hard disk to start the compact disk.
Step S416, determine whether the AES password check is passed.
After selecting to start the compact disc, the user needs to Input the password of the compact disc in a Basic Input Output System (BIOS) interface, check whether the password Input by the user is correct, if so, perform AES decryption to normally work, and perform step S418, otherwise, perform step S416.
Step S418, the compact disk executes the hard disk function thereof, and monitors the destruction signal.
After the switching unit selects to start the compact disc, the compact disc becomes an actual working hard disc, and normal reading and writing, installation of a starting operation system and other operations can be carried out on the compact disc. The bright disc is in a power-off state at this time. When the compact disc enters a normal working state, the compact disc controller can constantly monitor the destroying trigger signal, namely the destroying instruction.
Step S420, determining whether there is a destruction signal.
If the compact disc receives the destruction signal, step S422 is executed, otherwise, step S418 is executed.
In step S422, a data destruction function is performed.
When a destroy signal, namely a destroy instruction, is received, the compact disk controller immediately starts a data erase function to erase all data in the compact disk such as Flash. After the erasure is finished, the inside of the compact disc does not have any data, and the compact disc is in an unformatted initial state and can be used as a new disc. The flow is ended.
