Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a plurality of information processings such as recording information, erasing information and reproducing information on the same optical recording medium in a drive device for driving the optical information recording medium. Includes a novel optical information processing apparatus for accessing information processing simultaneously or concurrently, or arbitrarily and independently for each processing of each information, and a disc cartridge suitable for being mounted in the apparatus. Information processing system.

2. Description of the Related Art Conventionally, in a recording / reproducing apparatus for an information recording medium, information processing on the same information recording medium is generally performed by any one type of information processing selected from information recording, information reproducing, information erasing and the like. Therefore, once information recording is started, for example, other information processing, such as reproduction of information, cannot be performed on the same surface of the same information recording medium until the recording operation is completed. This is not a big problem on a magnetic tape or a medium having a small recording capacity because the time required for information processing such as recording and reproducing is short.

However, since an optical information recording medium such as a write-once type optical disc or a magneto-optical disc is a large-capacity recording medium, it takes a very long time to complete the process once recording or reproduction is started. Therefore, the recording or playback mode cannot be changed easily.

Further, since the number of kinds of information to be recorded is extremely large, the frequency of recording and reproducing of information is high. Therefore, once recording or reproduction is started, the opposite mode of reproduction or recording mode is set for a very long time. Not easily changeable.

Another technique for increasing the information transfer rate and the information recording density is disclosed in Japanese Patent Laid-Open No. 1-130374.
Japanese Patent Application Laid-Open No. 1-130376, Japanese Patent Application Laid-Open No. 1-130
It is disclosed in Japanese Patent No. 34766.

Among the above-mentioned three cases, JP-A-1-130374 and JP-A-1-130376 disclose a spiral information track formed on the same surface of a recording / reproducing area of an optical disk recording medium as an intermediate point of the recording / reproducing area. The optical disc recording medium is formed in opposite directions to each other on the inner side and the outer side, and the optical disc drive rotates the optical disc recording medium in one direction so that the first side is formed on the inner side of the optical disc recording medium. The above head is arranged and the second head is arranged on the outer peripheral side to perform information processing of recording and reproducing.

However, this technique distributes a certain amount of information in proportion to the linear velocities corresponding to the first head and the second head, respectively, and allows two optical heads to access each other at the same time, thereby recording and reproducing. However, there is a problem that one optical head cannot perform information processing at all.

The above-mentioned Japanese Patent Laid-Open No. 1-134766 uses an optical disk recording medium in which spiral information tracks formed in recording and reproducing areas on both sides of the optical disk recording medium are formed in directions opposite to each other. By rotating the optical disk recording medium in one direction, the first head is arranged on the front side of the optical disk recording medium and the second head is arranged on the rear side, and information such as recording and reproducing is always formed by both heads in a pair. The processing is performed.

However, in this technique, the relative movement speed in the rotation direction between the first optical head and the track on the optical disk and the relative movement speed in the rotation direction between the second optical head and the track on the optical disk. The feature is that the two optical heads are moved in the radial direction of the optical disc so that the value obtained by adding and is always constant. The two optical heads simultaneously access the heads to perform information processing. There is a problem that the optical head alone cannot process information at all.

Therefore, in a compact disc player or a video disc player, even if a write-once compact disc or a video disc is developed, recording and reproduction of information are performed in the same manner as the conventional audio tape recorder or video tape recorder. Cannot be performed simultaneously, and convenience in use cannot be improved.

Further, in a device using a large-capacity optical disk such as an image filing device, a huge amount of time is required for recording, reproducing, erasing, etc. of information, and while one person is using another person, Since it cannot be used, it is inconvenient to use because it is a device that is frequently used and often cannot be used immediately when needed.

As shown in FIG. 15 and FIG. 16, the disc cartridge 21 is made up of a hard plastic or the like and is a half of a case formed in an upper case 1 and a lower case 2.
And have. The upper case 1 and the lower case 2 are provided with spindle insertion holes 3 and 3 facing each other substantially in the center thereof, and a side portion (front side portion) on the insertion side of the spindle insertion holes 3 and 3 into the disk drive device. 2), head insertion holes 4 and 4 in the shape of long holes are opened facing each other.

The disc cartridge 21 includes the upper case 1
The lower case 2 and the lower case 2 are bonded to each other at the opening side to be assembled into a box shape, and the disk-shaped recording medium 6 is rotatably housed in the disk housing chamber 5 in the box. The disc cartridge 21 is inserted and mounted in a disc drive device in a specific one direction, and the disc-shaped recording medium 6 is rotationally driven in a specific one direction to record and reproduce information on the surface of the recording medium 6. , Erasing, etc. can only be performed.

On the other hand, as shown in FIG. 16, in a conventional disk drive device in which the disk cartridge 21 is mounted to record, reproduce, and erase information, a spindle motor 11 for rotating a disk-shaped recording medium 6 is used. An upper magnetic head 12 and a lower optical head 13 arranged to face the recording surface of the disk-shaped recording medium 6, a head fixing rod 175 for mounting the upper magnetic head 12 and the lower optical head 13, and The head feed shaft 169, the feed mechanism section 170 of the heads 12 and 13, and each of these devices 1

And 13 are arranged so that the two heads 12 and 13 can integrally read the recording information related to the upper recording surface and the lower recording surface of the disc-shaped recording medium 6. Therefore, the information transfer speed can be improved as compared with the one-head type disk drive device.

FIG. 18 is a block diagram of a part of an optical information processing apparatus according to an embodiment of the present invention. That is, with respect to the input / output of information in / from one disk-shaped recording medium 6 in one optical information processing apparatus, based on the respective access command signals input from the keyboards 73a and 73b of the workstations 73 and 74 at a plurality of locations, A plurality of head access drive devices 300, 3 that operate independently of each other
01 is incorporated into the optical information processing apparatus system 72 so as to correspond to the keyboards 73a and 73b of the workstations 73 and 74, respectively.

In the optical information processing apparatus system 72, in the area where the heads on the disk-shaped recording medium 6 are prohibited from accessing at the same time, the head that first starts the head access continues to access the present. In this case, the track access restriction control circuit devices 70a and 70b are installed to keep the other heads, which will be described later, from being accessed unless the former head access is completed.

That is, for example, the first workstation 73
In order to access the recording, reproducing, and erasing from the second workstation 74, it must be possible to access the second workstation 74 independently.

By the way, in the case where the preformat pattern on the disc-shaped recording medium 6 is the one shown in FIG. 18, track information (or guide groove or pregroove) 251 and sector information 250 having an address consisting of prepits are formed. A pre-format pattern such as is formed. A spindle hole 11a is formed in the center of the disk-shaped recording medium 6 so that the center of rotation and the center of tracking are coaxial. The disk-shaped recording medium 6 is put into practical use by being rotatably housed in a disk cartridge 21 not shown. Examples of the disc-shaped recording medium 6 having this structure include a write-once type optical disc, a phase change type optical disc, a magneto-optical disc, an optical tracking type magnetic disc, and the like.

In FIG. 38, the recording area of the disc-shaped recording medium 6 is divided into a plurality of blocks 254, and a pre-format pattern consisting of a guide groove or track 251 determined for each block and a sector 250 containing pre-pit address information is shown. It is a figure which shows the disk-shaped recording medium 6 formed.

That is, the access of the head for information processing such as recording of information or erasing of information is performed at least on the circumference of the same track 251 or the track 2 thereof.
In the vicinity of 51, it must be controlled so as not to overlap with the information processing access of other heads from the plurality of workstation keyboards 73 and 74. Because the recording film of the disk-shaped recording medium 6 is irradiated with a light beam from the optical head to generate heat,
This heat is high in the information recording light beam and the erasing light beam, and is low in the reproducing light beam. However, if heat is applied at a predetermined temperature or more than the predetermined amount of heat, the recorded information pits may be destroyed or the life may be deteriorated. This control circuit and device 70 are shown in FIG.

Information such as index information of recording information, defect position information of recording area, head access area range information, password, user code, ID information, security information, etc., specific to the information recording medium stored and peculiar to the information recording medium is stored. Since it is also possible to hold it, the head access operation unique to the information recording medium is possible.

As shown in FIG. 18, the access command from the workstation keyboards 73 and 74 to the optical information processing system 72 is sent to the semiconductor memory and C by the access restriction control circuits 70a and 70b of the track 251.
Access from the optical heads 12a and 12b to the track 251 and the sector 250 whose access is prohibited is prohibited by a signal from an IC memory including a PU or the like, and the semiconductor control element 71. The optical heads 12a and 12b are controlled to be accessible by designating different access permission areas such as the track 251, the sector 250, and the block 254.

In order to prevent the plurality of optical heads 12a and 12b from coming into contact with each other, a plurality of head feed guides or head moving spaces are correspondingly used to set the positions.

Drive devices for information recording media such as optical disks and magneto-optical disks include reproduction-only devices, write-once recording / reproducing devices, and erasing-type recording / reproducing devices.
When recording, reproducing, erasing, and the like of each device, it is convenient and convenient to use a device configured to operate as described below, including a known function, of the optical system head of the device.

(1) Reproduction Only Device The head scans the recording area to the target reproduction position while reading the mark. Play the desired information.

After the reproduction is completed, the head returns to the start position while reading the mark in the recording area again.

(2) Write-once type recording / reproducing apparatus Recording operation: In the reproducing mode, the head scans the recording area to the target recording position while reading the mark.

At the target recording position, the head changes to the recording mode and starts recording.

When the recording is completed, the head switches to the reproduction mode again and returns to the start position while reading the mark in the recording area.

Playback operation: While the head is reading the mark,
The recording area is scanned to the target reproduction position. Play the desired information. After the reproduction is completed, the head returns to the start position while reading the mark in the recording area again.

(3) Erase-type recording / reproducing apparatus: Erase operation: In the reproducing mode, the head scans the recording area to the target erase position while reading the mark.

The head changes to the erasing mode and starts erasing.

When the erasing is completed, the head switches to the reproduction mode again and returns to the start position while reading the mark in the recording area.

Recording operation A: In the reproduction mode, the head scans the recording area to the target recording position while reading the mark.

When the area for recording does not need to be erased, or when the area for recording needs to be erased but the apparatus is capable of overwriting, the head changes to the recording mode or the overwrite mode. Start recording.

When the recording is completed, the head switches to the reproduction mode again and returns to the start position while reading the mark in the recording area.

The target information is reproduced.

After the reproduction is completed, the head returns to the start position while reading the mark in the recording area again.

The recording operation and the erasing operation need to be able to operate independently and independently, but at the same time, it is necessary that one head can change modes such as recording → erasing and erasing → recording.

Therefore, the method of controlling the light beam intensity with one optical head to have the function of performing recording, erasing and reproducing and performing the recording, erasing and reproducing operation with one optical head is the most used. easy.

When each optical head is provided with information processing capability of recording, reproducing, and erasing information independently, the access manner of each head is the access method like the flow chart shown in FIG. It can also be used by functioning. For example, in the case of an erasable disc drive, the optical system head access operation can always perform a reproducing operation for both recording and erasing operations. It can be moved and accessed anywhere in the patterned area.

FIG. 5 is a layout view of a head feed guide, a head guide screw shaft, or a head movement space according to the embodiment of the present invention.

As is clear from the respective figures, the head feed guide, the head guide screw shaft, or the head moving spaces 14a to 14d are formed in the recording film in the disk radial direction from the vicinity of the center of the disk-shaped recording medium 6 to the radial outside. It is preferable that they are arranged radially over the entire area. Incidentally, 11c in the figure is a spindle.

Here, the head sliding space or head moving space of one head means a region through which the head moves when the one head is moved along a head guide means such as a corresponding head feed guide. If the areas of the two heads partially overlap with each other, the two heads may collide with each other, and thus the head moving space means a space that does not overlap with each other.

The head movement guide rails or the head movement spaces 14a to 14d simply show various head movement means or devices.

More specifically, FIG. 26 and FIG.
It is a figure which shows the head moving device of the system which moves a head with the screw-shaped feed shaft 169. This head moving device includes a laser beam transmitter 181, a prism 183,
From the mirror 182, the photodetector 184, etc. to the optical device 167.
Is configured.

Further, the rotating mirror 185 and the lens mechanism 168.
The optical head 13 is composed of the above. The optical head 13 and the optical device 167 integrally form a mechanism for moving the optical head 13 on the guide rail 14 by the rotation of the screw-shaped feed shaft 169.

FIG. 28 shows an example of a head moving device using a linear motor. In this head moving device, a linear motor is composed of a magnet 176, a coil 171, a base 179, and the like.

Therefore, a recording beam spot, a reproducing beam spot, and an erasing beam spot can be respectively emitted from one optical head according to use.

However, it is also possible to use the plurality of heads by combining heads such as a beam spot dedicated to recording, a beam spot dedicated to erasing and a beam spot dedicated to reproduction. If a head having two functions of reproducing and recording and a head having two functions of reproducing and erasing are used for each of the plurality of heads, the head can be moved independently from the start position to the position where information processing is started. It is more practical because it works with the head.

The range in which the head feed guide or the head movement space is formed is shown in FIG. 7, FIG. 11, FIG.
As shown in FIG. 14, the disk-shaped recording medium is inserted and mounted, and the disk-shaped recording medium is inserted into the disk-shaped recording medium in the vicinity of the optical information processing drive device in the vicinity of the vicinity where the outer circumference of the turntable 11 of the optical information processing device does not intersect the space extension.
