Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field to which the Invention Pertains] The present invention relates to a medium recording system, and relates to an optical disk plate used in an L-bearing head type optical disk device, which is a medium in which data is stored. The above is related to a medium recording system for an optical disk board having an optical storage section that stores and reproduces information using a laser beam. [Prior art] A conventional medium recording system uses a laser beam to write data. It consisted only of an optical storage section that performs data transfer (M, IB).

Next, a conventional medium recording method will be explained with reference to the drawings.

1(a), (1)), and (C) are a perspective view, a top view, and a record configuration diagram showing an example of an optical disk plate used as a medium in a conventional optical disk device.

In such conventional media recording methods, when writing data onto an optical disk board used in an optical disk device, the medium is irradiated with laser light as shown in Figures 1(a) and (C). It stores information by making holes (causing chemical changes).

When reading data, light is irradiated as shown in FIGS. 1(a) and 1(C), and the data is read using the reflected light.

In this way, when using the media recording method to write data onto an optical disk board, light is irradiated and holes are made on the optical disk board, making it impossible to rewrite or erase data in the same location. Become.

For example, after writing data, verification (reading the data and checking whether it was correctly written) is performed, and if there is an error, the previous history is written to an alternative record. At this time, the data of the record that was recorded earlier must be erased, but as mentioned earlier, it is impossible to go back to sleep.

Therefore, in a system using an optical disk device, a magnetic disk is equipped with another file device such as a device, and this file device is used to store attribute information (for example, defective information, unused information, erasure information, substitute information, chain information, etc.) are stored in a separately provided file device, and the information stored on the optical disk board is managed and controlled.

Therefore, if your system uses optical disk devices,
There was a drawback that a separate file device had to be installed for controlling the optical disk device.

[Purpose of the invention]

An object of the present invention is to provide a file storage system for attribute information (1) to provide a medium recording method that does not cause any damage.

That is, an object of the present invention has been devised to eliminate the two drawbacks mentioned above. On the body - Optical storage unit that stores and reproduces information using laser light and MQ of information using magnetic material 1. V, magnetic recording for reproduction 1, C divided into parts,
A media recording method that allows management and control of an optical disk device without a separate file device for controlling the optical disk device by storing information indicating attributes of an optical-traditional portion in a magnetic storage portion. Our goal is to provide the following.

[Structure of the invention]

The medium recording method of the present invention uses an optical storage section in which data is written and read using a laser beam and a magnetic material in an optical disk plate used as a recording medium in an L-shaped optical disk device. and a magnetic storage section for storing attribute information indicating attributes of data recorded in the optical storage section.

That is, the medium recording method of the present invention uses an optical storage section that uses a laser beam to write and read data, and a magnetic material in an optical disk board used in a moving head type optical disk device. A magnetic storage section is provided for writing and reading data, and the magnetic storage section stores information indicating attributes of the optical storage section (defect information, unused information, erase information, replacement information, voluno, label, chain information, etc.) By doing so, the access time can be improved and data can be easily updated.

[Explanation of Examples]

Next, embodiments of the present invention will be described with reference to the drawings.

2(a) and 2(b) are a top view and a central sectional view showing an embodiment of the present invention, and FIG. 2(a) shows a magnetic storage section MM on the optical disk plate 1. FIG. 2 (+) is a diagram showing the optical storage section ML, in which data recording in the optical storage section ML is performed by laser light, and data recording in the magnetic storage section MM is performed by the magnetic head 3. FIG. 2 is a diagram illustrating an outline of reproduction.

FIGS. 3(a) and 3(b) show management of the optical storage unit ML, lu
For control, ν of the data stored in the # section ML is written optically.
An example of information indicating 4 properties is magnetic ij2 (, M part MM)
)Kikomi! FIG. 3 is a diagram showing an example of a -r filter format.

It is impossible to write data to the optical storage section ML for the second time or later when data is written to the optical storage section ML at the same time.

Therefore, after writing data, it is necessary to read and verify the data to check whether it was written correctly. As a result of verification, if there is an error, that record 1 is defective, and the information indicating the defect must be recorded and the data must be rewritten in the alternative record J<. The reason for this defect is that, as mentioned earlier, it is impossible to write to the same location on a magnetic disk, which is done with a magnetic disk drive. Therefore, Figure 2 (a),
If it is recorded in the field of the defective record -f index shown in No. 3 and 1 in the magnetic storage section shown in (b), it can be easily used.

Also, when you want to delete used data, you can re-incorporate it into the optical storage unit ML as mentioned above,
However, as shown in FIG. 3 of the magnetic memory section MM? 7'I Image of the record you want to delete on the Borino bitmap
If you record 6 pieces of information, you can easily become an El Noh.

If you want to replace disk plate 1, use the polyurethane shown in Figure 3. - Record where the data was used in the bitmap, record information indicating the creation of the data in the volume root directory, and exchange.

In that case, I reinstalled the optical disc plate 1 and turned on the light. (How far is written in the 7' column of control side 1 of Tsukijibu P, 4 L, and what kind of data is written, which record is defective and which record is erased? There is no need to read out and examine the entire optical storage section ML in order to investigate the information, and this information can be obtained simply by cutting out 4N1 to the magnetic storage section, and access is also very quick.

〔Effect of the invention〕

The medium recording method of the present invention has a magnetic record 1f (
By making the part more powerful, the attributes of the data stored in the base part can be stored on the optical disk board integrated with the optical storage part, so there is an effect that a separate file device for storing attribute information is not required.

That is, the medium recording method of the present invention is to provide an optical storage section and a magnetic storage section on a disk board used in a ping head type optical disk device, and to store the base fertilizer 1 and the σ section in the magnetic storage section. By storing information indicating the attributes of the optical storage unit, access tightness of the optical storage unit and updating of data can be easily performed. This has the advantage that a separate file device is not required.
