Description

  The present invention relates to a read / write media device protection structure and method, and more particularly to a portable hard disk, notebook computer, personal digital assistant (PDA), optical disk drive, CD-R / RW drive, portable CD player, and the like. The present invention relates to a protection structure for a read / write media device having storage and read / write functions and a method thereof.

  As the technology of data processing equipment improves, today's computer hardware systems are no longer confined to conventional desktop computers, but notebook computers, tablet PCs, PDAs, mobile phones, MP3 players, portable CD players, and portable information. Many emerging computer-related products such as processing equipment have become widespread, and portable hard disks are not limited to notebook computers, but for example, advanced automobile navigation systems and image music systems in the automobile industry also require portable hard disks. For this reason, the application of data processing in information media has been accelerated.

  In times when this information is overflowing, needs for data access capacity, speed, data read / write quality, etc. are increasing day by day. Generally, high-capacity data access devices that have been conventionally used are, for example, hard disks, In both optical disk drives (CD-ROM), magnetic materials are coated on a plastic or metal substrate, data is stored using the logic structure of the magnetic field, and the spindle motor rotates at high speed when accessing data. Therefore, it is necessary to access data with a read / write head mechanically, and when the read / write head moves at a very fine interval on the disk while rotating 5,400 to 10,000, even a little Data access may be interrupted by external vibration Only Not, since the disk and read-write head is frictionally to each other, read-write head hits the disk, can even cause damage to the disk or read-write head.

  For this reason, as a means for solving such a problem, an improvement in which resonance is reduced by using a structural damping rubber is proposed. However, this method is inferior in reliability, and the hard disk and the optical disk drive are inconvenient. In particular, since it has a resonance effect in operation, the maximum stress tolerance level cannot be improved so much by the improvement method of the damping rubber. In addition, a forced interruption method that directly stops the operation of the hard disk or optical disk drive that has received external force has been proposed. However, since this method cannot stop power supply to the hard disk or optical disk drive, There is always a possibility that the data contained inside it will be lost again. Further, when the external force is removed, the user needs to set again so that the data of the hard disk or the optical disk drive can be operated again, which is very inconvenient for the user. Most importantly, in the above two methods, the hard disk and the optical disk drive are always in an operating state, and the impact resistance and earthquake resistance have a large difference compared with the performance in the non-operating state of the present invention (according to experimental data). When the operation state is changed to the non-operation state, the impact resistance is 150G to 1000G, and the earthquake resistance is 0.7G to 3G).

Current technology cannot solve the instability of data access using a mechanical read / write head in an environment subject to vibration of a conventional high-capacity data access device, and a solution was awaited to improve this situation. Has become a technical issue.

In view of the above problems, the object of the present invention is to dynamically protect the operation of the read / write media device and the intervention of external force (vibration, drop, etc.) will not cause data loss or corruption of the read / write media device. An object of the present invention is to provide a read / write media device protection structure and method.

  The protection structure provided by the present invention can protect many read / write media devices such as portable hard disks, notebook computers, personal digital assistants (PDAs), optical disk drives and CD-RW drives.・ When the writing media device is in operation, the detection unit detects the intervention of external force, and when it exceeds a certain value, this structure forcibly powers off the reading / writing media device and operates this device Disabling, increasing stress to the maximum, improving seismic and impact resistance. According to the experimental data, the impact resistance is changed from 150G to 1000G, and the earthquake resistance is changed from 0.7G to 3G.

  The detection unit of the present invention can improve the reliability of the read / write media device. In addition, the energy control unit of the present invention supplies power even when the read / write media device loses power supply and reads / writes. The head can be returned to the stop position, and the central processing unit records the state of use before receiving interference from an external force. When the external force is removed, the original state is restored again without any other settings. This is more convenient for the user's operation.

The method of the present invention includes at least the following procedures. It is judged whether the external force detected by the detection unit exceeds the critical point, then the central processing unit records and saves the state of the read / write medium, issues an interruption command, and the charge control unit sets the charge to the saturation point. If the saturation point has been reached, the central processing unit forcibly turns off the power supplied to the read / write medium, and after the power supply is cut off, determines whether the external force has already been removed by the detection unit and removes it. If the central processing unit recovers the power supply to the read / write medium, and the electric energy control unit determines again whether the electric energy has reached the saturation point, and if the electric energy control unit has not reached the saturation point, the central processing unit If the processing unit forced power interruption procedure is continued and the saturation point has been reached, the central processing unit will To restore the state of the read-write media.

The protection structure and method of the read / write media device according to the present invention protects the device by a method and design for forcibly turning off the power supply when the read / write media device is subjected to shock or vibration, and minimizes injury. can do.

  Detailed contents and techniques of the present invention will be described below with reference to the drawings.

  The protection structure and method of the read / write media device according to the present invention protects the device by a method and design for forcibly turning off the power supply when the read / write media device is subjected to shock or vibration, and minimizes injury. The main purpose is to do.

  Before describing the method of the present invention, the basic configuration of the present invention will be described first. FIG. 1 shows a diagram of the protection structure of the read / write media device of the present invention.

  The read / write media device protection structure 100 of the present invention includes the following units.

  First, the detection unit 10 is used to detect an external force and calculates a numerical value of the external force. When the external force is larger than a critical point set in advance in the structure 100, an impact signal is transmitted, and when the external force is removed, a recovery signal is generated. Handle each different situation and send a signal to the corresponding unit.

  The first arithmetic unit 20 notifies the central processing unit 40 of the recording of the usage state of the read / write media device protection structure 100 and notifies the central processing unit 40 of the recovery of the usage state of the read / write media device protection structure 100. When an impact signal is received, an interruption signal is issued, and when a recovery signal is received, a recovery signal is issued to handle different situations and send a signal to the corresponding unit.

The read / write medium unit 50 is used for storing and reading / writing data in the read / write media device protection structure 100 and includes a read / write head component and a storage function.
The switch unit 30 is used to control the power supply of the read / write media device protection structure 100 and performs a power on / off operation. When the recovery signal is received, the read / write medium unit 50 is turned on to start power supply.

  The charge control unit 70 is saturated when the read / write medium unit 50 is operated, and is discharged when the read / write medium unit is interrupted. The charge control unit 70 is used as a basis for restoring the use state of the central processing unit 40. It is a component having a discharge function, and can be a charge / discharge battery.

  The second arithmetic unit 60 is used to determine the status of the electric energy control unit 70, receives an interruption signal and transmits an interruption saturation signal when the electric energy is saturated, and the electric energy control unit 70 is already saturated to the central processing unit 40. When the state is informed and the recovery signal is received and the electric energy is saturated, the recovery saturation signal is transmitted.

  The central processing unit 40 is used for signal processing in the read / write media device protection structure 100 and recording and recovery of the use state of the read / write media device protection structure 100. When the interruption signal is received, the central processing unit 40 records the use state. When the power supply interruption process is prepared and the interruption saturation signal is received, the switch unit 30 is forced to perform the power supply interruption process. When the recovery saturation signal is received, the use state of the read / write media device protection structure 100 is recovered. .

  The above-mentioned units communicate with each other using signals shown in the figure.

  The read / write media device described above is a device having a read / write head component and a storage function, such as a portable hard disk, a notebook computer, a personal digital assistant (PDA), a portable CD player, an optical disk drive, and a CD-RW drive. be able to.

  Using the system described above, the read / write media device can be protected when subjected to shock or vibration, and the protection flow will be described in more detail. FIGS. 2-1 to 2-4 are flowcharts of the read / write media device protection structure of the present invention.

First, as shown in FIG. 2A, the recovery of the read / write media device protection structure 100 determines whether the external force detected by the detection unit 10 exceeds a critical point (procedure 200), and this critical point is read. If the critical point is not exceeded, the detection unit 10 continues to detect if the critical point is not exceeded, and if the critical point is exceeded, after the procedure 200, FIG. 3 enters the procedure A shown in detail in FIG. 3, and when the procedure A is entered, the detection unit 10 transmits an impact signal (procedure 201), and the first arithmetic unit 20 calculates the impact signal and then transmits it to the switch unit 30. (Procedure 202), after the switch unit 30 receives the impact signal, it notifies the central processing unit 40 (Procedure 203). At this time, the central processing unit 40 records / saves the state of the read / write medium unit 50 and sends an interruption command (procedure 210), and then the electric energy control unit 70 determines whether the electric energy has reached the saturation point. (Procedure 220) If the saturation point has not been reached, the operation of the read / write medium unit 50 is interrupted by an interrupt command (Procedure 240), and the read / write medium unit 50 is notified and the read / write head is returned to the stop position. This flow ends. Since this forced interruption is a part of the prior art, it is not within the scope of discussion in this flow. When the saturation point has been reached, the power supplied to the read / write medium unit 50 by the central processing unit 40 is forcibly cut off (procedure 230), and the power is cut off so that the read / write medium unit 50 is automatically The operation is stopped and the operation disabled mode is entered, and the procedure B is entered. As shown in FIG. 2-2, when the procedure B is entered, it is determined whether or not the external force has already been removed by the detection unit 10 (procedure 250), and the detection unit 10 continues the detection while continuing the power supply interruption. If it has already been removed, after the procedure 250, the procedure C shown in detail in FIG. 2-4 is entered. When the procedure C is entered, the impact signal is interrupted by the detection unit 10 (procedure 251). 60, the recovery signal is transmitted (procedure 252). Finally, after the switch unit 30 receives the recovery signal, the central processing unit 40 is notified (procedure 253). At this time, the central processing unit 40 restores the power supply to the read / write medium unit 50 (procedure 260), and subsequently determines whether the electric energy has reached the saturation point by the electric energy control unit 70 (procedure 280). If not reached, the forced power interruption procedure of the central processing unit 40 is continued (procedure 270). If the saturation point has already been reached, the central processing unit 40 finally sets the state of the previous read / write medium unit 50. Recovery (procedure 290) allows the user to continue to operate and use, completing this flow.

  3A and 3B are circuit diagrams of the portable hard disk according to the first embodiment of the present invention. Here, a circuit capable of obtaining an effect by taking a portable hard disk as an example will be described as follows.

  As can be seen from the figure, the resultant force in the three directions of the X-axis, Y-axis, and Z-axis detected by the detection unit 10 is an external force as referred to in the present invention, and when it exceeds a preset critical point, the variable load component 11 The negative value after adjustment of the load component 12 is notified to the first arithmetic unit 20, the impact signal is transmitted to the first switch unit 31, and the signal is further transmitted to the central processing unit 40. At this time, the central processing unit 40 saves the usage state of the hard disk 51 and determines whether or not the electric energy in the electric energy control unit 70 is saturated. The negative load value after adjustment by the load component 14 is notified to the second switch unit 32, the direct power supply is interrupted, and the detection unit 10 continues whether the external force is still present or already lower than the critical point. If it is detected and lower than the critical point, a recovery signal is issued to notify the first arithmetic unit 20, and further a recovery signal is transmitted to the first switch unit 31 to directly restore the power supply of the hard disk 51 and to the second arithmetic unit 60, it is determined whether the electric energy of the electric energy control unit 70 has already reached the saturation point. If the electric energy has reached the saturation point, the second arithmetic unit 60 Notifies the central processing unit issues a recovery saturation signal, to restore the state of use of the hard disk 51.

  This figure is a circuit diagram of the most basic portable hard disk. Of course, there are many other methods, but the gist of the present invention is to avoid and protect the loss due to shock and vibration. It is only an explanation.

  Next, FIG. 4-1, FIG. 4-2, FIG. 4-3, and FIG. 4-4 show flowcharts of the portable hard disk protecting method according to the first embodiment of the present invention.

  As shown in FIG. 4A, the portable hard disk protection structure first determines whether the external force detected by the detection unit 10 exceeds a critical point (procedure 300). If the critical point is not exceeded, the detection unit 10 continuously performs detection. If the critical point is exceeded, the procedure is shown in detail in FIG. Entering procedure A, entering procedure A, the impact signal is transmitted by the detection unit 10 (procedure 301), the impact signal is computed by the first arithmetic unit 20, and then transmitted to the switch unit 30 (procedure 302). After the unit 30 receives the impact signal, it notifies the central processing unit 40 (procedure 303). At this time, the state of the hard disk 51 is recorded / saved by the central processing unit 40 and an interruption command is transmitted (procedure 310), and then it is determined by the electric energy control unit 70 whether the electric energy has reached the saturation point (procedure 320). If the saturation point has not been reached, the operation of the hard disk 51 is interrupted via an interruption command (procedure 340), the hard disk 51 is notified, the read / write head is returned to the stop position, and this flow ends. For this reason, this part is a forced interruption and is a part of the prior art, so it is not within the scope of discussion in this flow. If the saturation point has been reached, the central processing unit 40 forcibly turns off the power of the hard disk 51 (procedure 330), and the power is turned off so that the hard disk 51 enters an automatic stop state and enters the inoperable mode. Step B is entered. Further, as shown in FIG. 4B, after the procedure B, it is determined whether or not the external force has been removed by the detection unit 10 (procedure 350), and the detection unit 10 continues the detection while continuing to cut off the power supply. Is already removed, after step 350, the procedure C shown in detail in FIG. 4-4 is entered. When the procedure C is entered, the impact signal is interrupted by the detection unit 10 (procedure 351), and the second calculation is performed. A recovery signal is transmitted by the unit 60 (procedure 352). Finally, after the switch unit 30 receives the recovery signal, the central processing unit 40 is notified (procedure 353). At this time, the central processing unit 40 recovers the power supply to the hard disk 51 (procedure 360), and then determines whether or not the electric energy has reached the saturation point by the electric energy control unit 70 (procedure 380). Then, the forced power interruption procedure of the central processing unit 40 is continued (procedure 370). When the saturation point has already been reached, the central processing unit 40 finally recovers the state of the previous hard disk 51 (procedure 390). Ends.

  5A and 5B are circuit diagrams of the optical disk processing apparatus according to the second embodiment of the present invention. Here, a circuit capable of obtaining an effect as an example of an optical disk processing apparatus will be described as follows. However, since the optical disk processing apparatus is used as an alternative device for a portable hard disk, it is almost the same as the circuit diagram of the first embodiment. The description is omitted here.

  FIGS. 6-1, 6-2, 6-3, and 6-4 are flowcharts of the protection method of the optical disk processing apparatus according to the second embodiment of the present invention.

  As shown in FIG. 6A, the protection structure of the optical disk processing apparatus first determines whether the external force detected by the detection unit 10 exceeds the critical point (procedure 400). This critical point is determined by the optical disk processing apparatus. If the critical point is not exceeded, the detection unit 10 continues the detection. If the critical point is exceeded, the procedure is shown in detail in FIG. When entering procedure A, entering procedure A, an impact signal is transmitted by the detection unit 10 (procedure 401), and further, the impact signal is computed by the first arithmetic unit 20, and then transmitted to the switch unit 30 (procedure 402). After the switch unit 30 receives this shock signal, it notifies the central processing unit 40 (step 403). At this time, the state of the optical disk processing unit 52 is recorded / saved by the central processing unit 40 and an interruption command is transmitted (step 410). Subsequently, the electric energy control unit 70 determines whether the electric energy has reached the saturation point ( Step 420) If the saturation point has not been reached, the operation of the optical disk processing unit 52 is interrupted by an interruption command (step 440), and the optical disk processing unit 52 is notified to return the read / write head to the stop position. Ends. Since this part is a forced interruption and is part of the prior art, it is not within the scope of discussion in this flow. If the saturation point has already been reached, the central processing unit 40 forcibly cuts off the power supplied to the optical disc processing unit 52 (step 430), and the optical disc processing unit 52 is automatically stopped because the power is cut off. Enters the inoperable mode, and further enters procedure B shown in FIG. 6-2. When procedure B is entered, it is determined whether the external force has already been removed by the detection unit 10 (procedure 450), and the power supply interruption is continued. However, if the detection unit 10 continues detection and the external force has already been removed, after step 450, the procedure C shown in detail in FIG. 6-4 is entered. After interrupting (procedure 451), the second arithmetic unit 60 transmits a recovery signal (procedure 452), and finally, after the switch unit 30 receives this recovery signal, And notifies the central processing unit 40 (Step 453). At this time, the central processing unit 40 restores the power supply to the optical disk processing unit 52 (procedure 460), and subsequently determines whether the electric energy has reached the saturation point by the electric energy control unit 70 (procedure 480), and has not reached the saturation point. In this case, the forced power interruption procedure of the central processing unit 40 is continued (procedure 470). If the saturation point has already been reached, the central processing unit 40 finally recovers the state of the previous optical disk processing unit 52 (procedure). 490), this flow ends.

  As can be seen from the two examples above, all of the alternative devices listed as examples are devices with read / write head components and storage capabilities, all of which are heavily damaged by shock and vibration, In view of this point, the present invention provides a particularly greatly improved and innovative creation to solve today's problems.
