Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an information processing apparatus such as a portable personal computer (hereinafter referred to as a personal computer) equipped with a magnetic recording device and a portable workstation.

[0002]

2. Description of the Related Art In recent years, there has been a single magnetic disk device for recording and storing information (data) in portable personal computers and portable workstations, which tend to be miniaturized and have severe cost restrictions. Is provided.

By the way, this magnetic disk device has been improved in information processing capacity of a portable personal computer or the like and has been designed for high density recording. With the increase in recording capacity, important data is stored in the magnetic disk device. It is being recorded more often.

However, if the built-in magnetic disk device fails, the data stored in it cannot be read, and if particularly important data is stored, the user suffers a great deal of damage. Will be received.

[0005]

As described above, in the conventional information processing apparatus, if the magnetic recording device incorporated in the information processing apparatus fails, the stored data cannot be read out, and thus there is a problem in the storage safety. there were.

The present invention has been made in order to solve such a problem, and it is possible to multiplex and store data of a specific file in a plurality of magnetic recording devices, and to enhance the safety of data storage. The object is to provide an information processing device capable of performing

[0007]

In order to achieve the above-mentioned object, an information processing apparatus of the present invention includes a first magnetic recording apparatus for recording and storing a specific file, and a plurality of files including the specific file. A second magnetic recording device for recording and storing, a means for writing the data to the first and second magnetic recording devices when a data write request is made with the specific file name, and the specific file And a means for writing the data to the second magnetic recording device when a data write request is made with a file name other than the above.

[0008]

In the present invention, the data is stored in the first and second magnetic recording devices, the attributes of which are determined by the file name. For example, when a data write request is made with a specific file name, the data is written to the first and second magnetic recording devices. Further, when there is a data write request with a name other than the specific file name, the data is written in the second magnetic recording device.

That is, important data having a specific file name is multiply stored in the first and second magnetic recording devices.

As a result, even if the second magnetic recording device fails, important data can be read by the first magnetic recording device, and the safety of data storage is improved.

Embodiments of the present invention will be described below in detail with reference to the drawings.

FIG. 1 is a perspective view of an information processing apparatus according to an embodiment of the present invention.

As shown in FIG. 1, a portable personal computer (hereinafter referred to as a personal computer) as an information processing device.
1, a keyboard 2 as an input device for inputting a file name and data and a display 3 as a display device are provided. In addition, this personal computer 1 has a 2.5-inch type of 40M as the first magnetic recording device.
A magnetic disk device 4 having a recording capacity of B and a magnetic disk device 5 having a recording capacity of 500 MB of a 3.5 inch type are built in as a second magnetic recording device.

The structure of the main part of the personal computer 1 will be described in detail.

As shown in FIG. 2, a CPU 6, which controls the operations of the keyboard 2, the display 3, and the magnetic disk devices 4 and 5, is connected via a bus 7. The magnetic disk device 5 includes a plurality of files 5a to 5a.
It is divided into c. An operating system (hereinafter referred to as OS) is stored in the file 5a, important data having a specific file name is stored in the file 5b,
General data 5c is stored in the file 5c.
The magnetic disk device 2 stores important data 3b that is the same as the important data 3b having a specific file name in the magnetic disk device 3.

Next, the data writing operation of the personal computer 1 will be described.

First, when the personal computer 1 is powered on, the CPU 6 reads the OS of the file 5a and the write control and the call control to the magnetic disk devices 4 and 5 become possible.

When a data write request is made by the user operating the keyboard 2, the CPU 6 sorts the files based on the file name of the input data, and the data is written to the respective magnetic disk devices 4 and 5. .. Then, when the writing is completed, the character of the writing is displayed on the display 3.

The data sorting operation at this time is performed based on the flowchart shown in FIG.

First, when data and a file name for this data are input from the keyboard 2 (step 30)
1), this file name is previously assigned to the file 5 by the CPU 6.
Attribute determination is made as to whether or not the file matches the files recorded in b and 5c (step 302). If the file name is a file other than a specific file, this data is stored in the file 5c of the magnetic disk device 5 together with the file name.
(Step 303). If the file name is a specific file, this data is stored in the file 5 of the magnetic disk device 4 and the magnetic disk device 5 together with the file name.
It is multiplexed and stored in b (step 304). Therefore, at the stage of inputting the file name, the user inputs the file name by distinguishing general (less important) data from important data. For example, when saving important data, the user determines a specific file name to save in the file 5b and inputs it.

Next, the data read operation of the personal computer 1 will be described. When the file name to be read is input following the data read request by the user's operation of the keyboard 2, the attribute determination is performed by the CPU 6 as described above, and the individual magnetic disk devices 4 and 5 independently perform the file search. Be seen. Then, the data retrieved by each of the magnetic disk devices 4 and 5 is displayed on the display 3 by the CPU 6.

As described above, according to the information processing apparatus of the present embodiment, the magnetic disk device 5 is brought into a hardware failure state (device failure) or a software failure state (program runaway, etc.). Even if the stored important data is lost or cannot be recalled, the important data before the failure is redundantly stored (backed up) in the magnetic disk 4 and is important because the important data can be read from the magnetic disk device 4. No data loss.

For example, if the magnetic disk 5 is damaged,
If only S can be activated, data can be read from the magnetic disk device 4 and displayed on the display 3 or output to an external recording device or the like.

In the present embodiment, the general (commercially available) 3.5-inch type and 2.5-inch type magnetic disk devices having different storage capacities are built in the personal computer, but in the case of the laptop type workstation, Each of the two magnetic disk devices requires a storage capacity of several hundred MB. If it is possible to reduce the size and increase the capacity of magnetic disk devices in the future, it is possible to install two magnetic disk devices of the same capacity (for example, two 2.5-inch types).

[0025]

As described above, according to the information processing apparatus of the present invention, the first and second specific files can be selected.
The data can be multiplexed and stored in the magnetic recording device. As a result, it is possible to improve storage safety when data is stored in the information processing device.
