Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning device for cleaning a magnetic head and / or an optical pickup (objective lens) of a magneto-optical disk drive, and an optical pickup for an optical disk drive or a magneto-optical disk drive. Cleaning device for cleaning the objective lens).

[0002]

2. Description of the Related Art As a cleaning device for cleaning both a magnetic head and an optical pickup of a magneto-optical disk drive, a polishing sheet for lightly polishing the magnetic head surface is attached to a disk medium surface facing the magnetic head. A configuration in which a brush is implanted on the surface of the disk medium facing the pickup is known (see, for example, Japanese Patent Application Publication No. 6430 and 1995 Patent Application No. 6431).

As a magneto-optical disk, there is a mini-disk proposed and commercialized by Sony Corporation as a recording medium for music signals, in addition to a disk used as an external storage device of a computer. This mini disk employs a magneto-optical recording method, and uses both a magnetic head and an optical pickup for recording, but uses only the optical pickup for reproduction. Recordable disc cartridges include:
A read-only and recordable disk cartridge housing has an erasure prevention claw not provided in a read-only disk cartridge and a mechanically or physically detectable recordable disk cartridge. Holes are provided.

FIG. 2 is a plan view of a read-only disk cartridge, and FIG. 3 is a plan view of a recordable disk cartridge. Reference numeral 40 denotes an identification hole for identifying a recordable disk cartridge, and reference numeral 42 denotes an erroneous erasure prevention claw. Recording is possible when the erroneous erasure prevention claw 42 is pushed up in the upper right direction in FIG. Needless to say, the recordable disk cartridge contains a recordable magneto-optical disk medium, and the read-only disk cartridge contains a non-recordable optical disk. Even if a disc cartridge without the identification hole 40 is loaded into the recording / reproducing apparatus, it is recognized as a read-only disc cartridge, and the recording mode is not set. Of course, even if it is a recordable disc cartridge, if the erroneous erasure prevention claw 42 is set, even if it is loaded into the recording / reproducing apparatus, recording is not possible, and only the reproduction mode can be selected.

As a cleaning device capable of cleaning both the magnetic head of such a magneto-optical disk drive device and the objective lens of the optical pickup, a recording medium contained in a recordable disk cartridge is provided on a disk surface facing the optical pickup. A configuration is known in which a hair is implanted for cleaning an objective lens of an optical pickup, and a magnetic head cleaning sheet for cleaning the magnetic head is attached to a disk surface facing the magnetic head (for example, a patent application published in 1995). No. 6430 and 1995 Patent Application Publication No. 6431
No.). In order to clean the magnetic head, it is necessary that the drive device can be set to the recording mode. In the conventional example, a recordable disk cartridge is used.

Further, as a cleaning device for cleaning an optical pickup (object lens) of a disk cartridge type, a configuration in which a brush or the like is implanted on a surface of a disk medium facing the optical pickup is well known (for example, in 1996). Patent Application Publication No. 34008).

[0007]

In the conventional example of cleaning both the magnetic head and the optical pickup of the recording / reproducing apparatus (or the recording apparatus), the conventional apparatus operates in the recording mode when cleaning the magnetic head and the optical pickup of the recording / reproducing apparatus. Must use a recordable disc cartridge.
However, in the mini-disc system, when operating in the recording mode, the TOC provided in the central portion of the disk medium has a time corresponding to the recording time or the recording amount.
Information for managing the recording start position in the (table of contents) area (specifically, the user TOC area)
Each time the magnetic head is rewritten and cleaned, the magnetic head starts from the outer side in the disk radial direction. This means that if cleaning in the recording mode is repeated until recording to the entire capacity of the disc is completed, the recording mode can no longer be selected and cleaning cannot be performed. If you still want to clean it, you must erase any records to make room. In extreme cases, if you forget to start and end the cleaning, you must erase the record on the disc for the next cleaning.

It is an object of the present invention to provide a cleaning device which can clean a magnetic head and / or an optical pickup without such trouble.

In a cleaning device for cleaning only an optical pickup, a brush or the like is conventionally planted on a region for recording music or the like, specifically, on the outer peripheral side of a TOC region, and the objective lens is cleaned by the brush. In the meantime, it was important to prevent access errors from occurring. This is because there is a risk of causing the user to mistake the device as a failure. Further, in the structure in which the disk medium is housed in the cartridge, if the brush is too long, it will hit the inner surface of the cartridge housing and deform, so that there is a restriction that the brush cannot be too long. If the brush is short, it will not reach the objective lens surface of the optical pickup, and the optical pickup cannot be cleaned.

[0010] In view of such problems, an object of the present invention is to provide a cleaning device that can more easily clean a magnetic head and / or an optical pickup.

It is another object of the present invention to provide a cleaning device which can surely clean an optical pickup without troublesome operation.

Another object of the present invention is to provide a cleaning device which can clean a magnetic head of a magneto-optical disk drive by a simpler operation.

[0013]

According to the present invention, in a read-only disk medium, a magnetic head cleaning member is disposed on a surface facing the magnetic head, and the optical pickup is cleaned at a predetermined position on the surface facing the optical pickup. An optical pickup cleaning member is arranged, and medium identification information indicating a recordable disc is recorded as management information. The read-only disc is housed in a cartridge housing having an identification member indicating a recordable disc cartridge. In other words, the disc drive is mistaken for a recordable disc cartridge while using a read-only disc medium.

With this configuration, the recording mode can be selected in the recording apparatus or the recording / reproducing apparatus, and both the magnetic head and the optical pickup can be cleaned.

By recording management information indicating an unrecorded area starting at a recording start position included in the predetermined range of the magnetic head cleaning member on the read-only disk medium,
If there is a recordable area, the disc drive can be mistaken for it, and the magnetic head can be cleaned by the recording operation on the unrecorded area.

By setting the unrecorded area to have a width corresponding to a predetermined time required for cleaning the magnetic head as a recording time, the recording operation can be automatically stopped after the magnetic head has been cleaned for a predetermined time. . Alternatively, even if information indicating the remaining recordable time corresponding to a predetermined time required for cleaning the magnetic head is recorded on the read-only disk medium, the recording operation can be automatically stopped after a predetermined time. it can.

By using a cartridge housing that is substantially the same as the cartridge housing of the recordable disc cartridge, the cartridge can be easily manufactured at low cost.

By forming an opening for adhering a predetermined liquid agent to the magnetic head cleaning member in the housing wall of the cartridge housing facing the magnetic head cleaning member, it is possible to cope with wet cleaning.

In the present invention, an optical pickup cleaning member for cleaning the optical pickup is disposed on the surface of the disk medium facing the optical pickup, on the inner side or on the inner boundary of the area where the recording management information is recorded. Since the management information and the recording information (for example, music) are recorded at a high density in the area where the recording management information is recorded and on the outer peripheral side thereof,
If an optical pickup cleaning member, for example, a brush is disposed there, a disk error is likely to occur. When a disk error occurs, the disk drive no longer rotates the disk medium. If the magnetic head is also cleaned, the magnetic head cannot be cleaned. However, generally, inside the area where the record management information is recorded,
Although medium management information including medium identification information is recorded,
Due to the low data density, even if there are some obstacles,
There is no error in optical reading. That is, since a disk error is less likely to occur, a relatively large-sized optical pickup cleaning member can be used.

In both the recording / reproducing apparatus and the reproduction-only apparatus, the optical pickup always moves from the vicinity of the boundary between the recording area for recording management information and the recording area for basic medium information to the inner circumference side to read the basic medium information. By arranging the optical pickup cleaning member inside or on the boundary inside the area where the recording management information is recorded, the optical pickup can be reliably cleaned.

Further, both the recording / reproducing device and the reproduction-only device usually perform the focus adjustment operation of the optical pickup.
This is performed in the vicinity of the area for recording the basic medium information, which is inside the area for recording the recording management information. Therefore, by arranging the optical pickup cleaning member inside the area where the recording management information is recorded and at the position where the focus adjustment operation is performed, the optical pickup can be cleaned at the time of the initial focus adjustment operation. In the focus adjustment operation, since the optical pickup approaches the disk medium surface very close, the optical pickup cleaning member can be very short.

According to the present invention, there is also provided a cleaning device in which a magnetic head cleaning member for cleaning the magnetic head of the magneto-optical disk drive is disposed within a predetermined range of a surface of the disk medium facing the magnetic head. Records the information of the recording start position included in the predetermined range and the information of the recording time of the disk medium in a non-updateable manner,
In addition, the recording start position and the recording time of the disk medium are set such that the remaining recordable time of the disk medium is a predetermined time required for cleaning the magnetic head.

By making the recording start position non-updatable, the empty area is not eventually lost even by the sequential cleaning operation (that is, the recording operation). That is, there is no need to perform an operation of deleting a voice or the like recorded by the cleaning operation, and the operability is significantly improved.

Further, by setting the recording start position and the recording time of the disk medium so that the remaining recordable time of the disk medium is a predetermined time required for cleaning the magnetic head, the predetermined time can be reduced. The cleaning is automatically terminated by the cleaning operation, and the operability is improved.

By making the disk medium a non-recordable disk medium, for example, a read-only disk medium, the recording start position information and the recording time information can be simply made unupdateable.

The disk medium is a recordable disk.
By being accommodated in a cartridge housing having an identification member indicating a cartridge, it is possible to mistakenly recognize that recording is possible on the magneto-optical disk device.

By forming an opening for adhering a predetermined liquid agent to the magnetic head cleaning member in the housing wall of the cartridge housing facing the magnetic head cleaning member, it is possible to cope with wet cleaning.

[0028]

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

FIG. 1 shows a half sectional structure of a disk medium according to an embodiment of the present invention. In this embodiment, a read-only disk medium is accommodated in a cartridge housing of a recordable disk cartridge (that is, the cartridge housing shown in FIG. 3). Normally, the lead-in TO of the disk medium 10
In the C area 12, medium identification information indicating the type of the disk (for recording / reproduction / reproduction only), medium basic information such as recording power and recording time are recorded. In the present embodiment, recording is possible as medium identification information. The information indicating the disk medium is recorded. Thereby, when the recording / reproducing apparatus is loaded with the cartridge of the present embodiment, the identification hole of the cartridge housing,
Lead-in TOC area 1 of the contained disk medium
From both of the medium identification information, it can be recognized that recording is possible.

The disc medium 10 has a predetermined margin, a lead-in TOC area 12, and a user TOC area 14 for managing recorded information of the user (in the present embodiment, rewritable, but in this embodiment, ), A recorded area 16 and an unrecorded area 18 which can be recorded in the management information of the user TOC area 14. Although the disk medium 10 of this embodiment is a read-only disk, the information in the lead-in TOC area 12 is the same as that of a recordable disk. On a read-only disc,
Information to be recorded in the user TOC area 14 is recorded in the lead-in TOC area.

A magnetic head cleaning sheet 20 for cleaning the magnetic head 30 is attached to almost the entire surface of the disk medium 10 facing the magnetic head 30. The magnetic head cleaning sheet 20 is generally made of a sheet material coated with a nonwoven fabric, a synthetic fiber flocking, or an abrasive. However, the magnetic head cleaning sheet 20 can clean the magnetic head 30 without damaging the head surface. Other materials may be used if desired. The magnetic head cleaning sheet 20 need not cover the entire surface of the disk medium, but may cover at least the unrecorded area 18. By sticking the magnetic head cleaning sheet 20 over the entire surface in the circumferential direction, no unevenness occurs in the circumferential direction. By sticking the magnetic head cleaning sheet 20 to the radial end, even if the user forgets the cleaning end operation from the start of the cleaning in the recording mode, while the recording operation is performed to the end,
The magnetic head 30 does not bounce at the step portion at the end of the magnetic head cleaning sheet 20.

The recorded area 16 is roughly composed of three sub-areas 16a, 16b and 16c. In the innermost sub-region 16a, a voice message of cleaning start or usage is recorded. The central sub-region 16b has no sound for a considerable time (for example, about 30 minutes), and the optical pickup 3
A brush 22 or the like for cleaning the optical pickup 32 (the objective lens thereof) is implanted on the surface of the medium facing 2. Brush 22
May have a diameter of about 1 mm or less and a round cross section. In the outermost sub-region 16c, a voice message of cleaning end is recorded.

In the present embodiment, the portion composed of the sub-region 16a and the sub-region 16b is designated as track # 1, and
Let c be track # 2. By specifying the reproduction of the track # 2, the optical pickup 32 can quickly operate the sub area 16b.
, During which the objective lens of the optical pickup 32 is cleaned. The portion composed of the sub-regions # 16a, 16b and 16c may be the track # 1, but the sub-region 16b
Playback must be continued for the time required to pass through.

At the center of the disk medium 10, a metal center plate 24 is mounted.

The method of use of this embodiment and the operation during use will be described.

When the recording / reproducing apparatus is loaded with the cleaning device of the present embodiment, the recording / reproducing apparatus checks the presence / absence of the identification hole 40 of the cartridge housing and the state of the erroneous erasure prevention claw 42 and the optical pickup 32 to disc medium. 10
Is read from the lead-in TOC area 12. In the present embodiment, the same cartridge housing as that of the recordable disk cartridge is employed.
In the lead-in TOC area 12, medium identification information indicating a recordable disc is recorded.
4, the recording / reproducing apparatus recognizes that the loaded disk cartridge is recordable. Therefore, the user can select a recording mode.

In the information of the user TOC area 14, the recording start position is located at the innermost position of the unrecorded area 18 (recorded area 16).
When the user selects the recording mode, the recording / reproducing apparatus sets the unrecorded area 1
8, the magnetic head 30 and the optical pickup 32 are sent to the innermost position, and a recording standby state is set. During this movement, the optical pickup 32 passes through the recorded area 16, so that the objective lens surface is cleaned by the brush 22 in the sub area 16b. By the recording start operation by the user, the magnetic head 30 approaches a position in contact with the medium surface of the disk medium 10 (actually, the magnetic head cleaning sheet 20), and starts the recording operation. During the recording operation, since the magnetic head 32 is in contact with the magnetic head cleaning sheet 20, it is cleaned during this time.

In response to the recording end operation by the user, the recording / reproducing apparatus ends the recording, floats the magnetic head 30 and returns to the user TOC area 14, and the contents (for example, track #) corresponding to the recording operation at the time of cleaning. 2 is recorded, and the user TOC information is rewritten to the next recording start position). However, since the disk medium 10 of this embodiment is a read-only disk medium, the user TOC information is not rewritten regardless of this rewriting operation. Cleaning of the magnetic head 30 in the next recording mode is also started from exactly the same position. In the case of a recording / reproducing apparatus for verifying rewriting of the user TOC information, a TOC rewriting error will be displayed, but still, there is no hindrance to the next cleaning.

When it is desired to clean the optical pickup of the recording / reproducing device or the reproduction-only device, the following is performed. In the case of a recording / reproducing apparatus, reproduction is started by designating a reproduction mode, and in the case of a reproduction-only apparatus, reproduction is simply started. By the reproduction start operation, the apparatus starts reproduction of the track # 1, and a reproduction start message or a usage message recorded in the sub area 16a is reproduced. Next, the user operates reproduction of track # 2. As a result, the optical pickup 32 passes through the sub-region 16b at high speed, and during that time, the brush 22 strokes and cleans the objective lens surface of the optical pickup 32. Upon entering track # 2 (sub-region 16c) past sub-region 16b, a cleaning complete message is played. In particular, even if the user does not perform the operation of stopping the reproduction, since no more information is recorded, when the reproduction of the track # 2 is completed, the reproduction automatically ends, that is, the cleaning ends.
The device stops working. In the recording / reproducing apparatus, the magnetic head 30 is kept floating during the reproducing mode.

The cleaning of the magnetic head is preferably performed by a wet method. For this purpose, isopropyl alcohol or the like is adhered to the magnetic head cleaning sheet 20 to perform cleaning. In this embodiment, isopropyl alcohol can be attached to the magnetic head cleaning sheet 20 from the outside of the cartridge.
As shown in FIG. 4, a slit 24 is formed in a cartridge housing on a surface of the magnetic head cleaning sheet 20. An isopropyl alcohol or the like is applied to the magnetic head cleaning sheet 20 through the slit 24. Magnetic head cleaning sheet 20
The isopropyl alcohol applied to the magnetic head cleaning sheet 20 impregnates the inside of the magnetic head cleaning sheet 20 to melt the adhesive for bonding the magnetic head cleaning sheet 20 to the disk medium 10 or to damage the material of the disk medium 10 itself. There can be. To prevent this, for example, the entire surface of the magnetic head cleaning sheet 20 that adheres to the disk medium 10 is coated with a coating that prevents the impregnation of alcohols, and the coating layer is adhered to the disk medium 10. preferable.

The mini disc is also used as an auxiliary storage device of a computer. In such a case, the cleaning start message and the cleaning end message are recorded as data signals having similar contents instead of voice.

A sheet material other than the magnetic head cleaning sheet 20, for example, a nonwoven fabric or a synthetic fiber flocking may be used as long as the magnetic head 30 can be cleaned without damaging the head surface.

Although a mini disk has been described as an example, the present invention can be applied to other magneto-optical disks for cleaning both the magnetic head and the optical pickup.

Next, an embodiment will be described in which the optical pickup can be more reliably cleaned without troublesome operation. FIG. 5 shows a sectional structure (a) of the embodiment and a timing chart (b) of a focus adjustment operation of the optical pickup. The same components as those in FIG. 1 are denoted by the same reference numerals. This embodiment is also housed in a cartridge housing, as in the embodiment shown in FIG. In the present embodiment, an optical pickup cleaning member 34 such as a brush for cleaning the optical pickup 32 is attached to the user TOC area 1.
4 are arranged in the lead-in TOC area 12 inside. Even in the lead-in TOC area 12, it is preferably arranged at a position where the focus adjustment operation of the optical pickup 32 is performed. A cleaning completion message is recorded in the innermost area 36 of the recorded area 16 (ie, track # 1).

Although the medium basic information is recorded in the lead-in TOC area 12 as described above, the data amount is small and the recording data density is low, so that even if a brush or the like is implanted, a disk reading error hardly occurs. . When a disk reading error occurs, any reproduction operation and recording operation cannot be accepted thereafter, and it is not preferable because the magnetic head cannot be cleaned. The medium basic information is recorded in a very narrow width adjacent to the user TOC area 14 even in the lead-in TOC area 12, and the disk drive usually faces the boundary between the lead-in TOC area 12 and the user TOC area 14. Optical pickup 32 near the position
When the disk rotates, the optical pickup 32 is moved to the inner peripheral side by a distance sufficient to read the medium basic information from the boundary line. In some cases, the optical pickup 32 is simply moved slightly inside from the boundary line. Therefore, for example, even if one or several flexible fibers are spotted on the boundary between the lead-in TOC area 12 and the user TOC area 14 in a spot shape, the flexibility of the fibers is added, and a considerable cleaning effect is obtained. be able to.

When a disk cartridge is loaded,
First, the disk drive device reads the lead-in TOC area 12
Within this, the focus of the optical pickup 32 is adjusted. In this focus adjustment operation, at the same time as or before or after the optical pickup 32 suddenly approaches the disk medium surface to about 0.5 mm, the disk medium rotates, and then the optical pickup 32 is brought into a state where the signal recording surface of the disk medium 10 is focused. ,
The distance between the disk medium 10 and the optical pickup 32 is adjusted. During this time, the focus adjustment operation is performed exclusively for the disk medium surface, and the recording signal reading operation is not performed. Only when the disk medium is in focus, the medium basic information in the lead-in TOC area 12 is read, and if there is no problem, the user TOC area 14 is further read.
Go to read the management information recorded in.

When the optical pickup cleaning member 34 is disposed at the focus adjustment operation position in the lead-in TOC area 12, as shown in FIG. 5B, the cleaning is first performed when the optical pickup cleaning member 34 is loaded in the disk drive. The optical pickup 32 is cleaned during the focus adjustment operation,
The optical pickup cleaning member 34 may be very short as compared with the case of cleaning at the time of normal reproduction. That is, since the optical pickup 32 approaches the disk medium surface to about 0.5 mm, if the optical pickup cleaning member 34 is implanted at the position of the focus adjustment operation, the length of the optical pickup cleaning member 34 (or the length from the disk medium surface). (Height) may be about 1 mm, and if it is so short, it is hardly deformed even when housed in the cartridge housing. Even if there is an individual difference in the focus adjustment operation position, it can be handled by the flexibility of the fibers or fiber bundles constituting the optical pickup cleaning member 34.

When the optical pickup cleaning member 34 is arranged at a position other than the focus adjustment operation position, the optical pickup 32 needs to be longer than that shown in FIG. Be cleaned. When the recorded information in the user TOC area 14 can be read normally, the cleaning of the optical pickup 32 has been completed.

When the track # 1 is reproduced, a message indicating the completion of cleaning is output as a voice for confirmation.

When the optical pickup cleaning member 34 is the user TO
The user T may slightly extend over the C area 14.
Since information for managing recording information is recorded in the OC area 14 at a high density and a disk reading error is easily caused by the cleaning member 34, it is better not to let the cleaning member 34 enter the user TOC area 14 as much as possible. Good. When the reading error of the user TOC area 14 has occurred, that is, since the cleaning of the optical pickup 32 has been completed, the original purpose has been achieved, but the user is unnecessarily anxious. Is not preferred. In this state, the magnetic head cannot be cleaned thereafter.

In the above embodiment, the recording mode operation for cleaning the magnetic head 30 is stopped when recording on the unrecorded area 18 is completed. Since excessive cleaning of the magnetic head 30 is not preferable for the magnetic head 30, the magnetic head 30
It is preferable to stop the recording operation automatically after a certain period of time suitable for the cleaning of. For this purpose, for example, it is sufficient that the recordable free space (the size of the unrecorded area 18) is equivalent to a time suitable for cleaning the magnetic head 30. Time magnetic head 3
The recording time of the disk medium 10, the recording start position, and the size of the unrecorded area 18 after the recording start position are adjusted so that the time suitable for cleaning of 0 is reached. For example, in the lead-in TOC area 12, recording time information is recorded in addition to the medium identification information, and the recording time information is set to a desired value shorter than usual.

By doing so, the recording / reproducing apparatus determines that the recording operation has reached the full recording state during the recording operation for a certain period of time and stops the recording operation. Therefore, it is possible to prevent the magnetic head 30 from being cleaned too much, The operability is improved by automatically ending the cleaning.

[0053]

As can be easily understood from the above description, according to the present invention, both the magnetic head and the optical pickup can be cleaned. Even when the magnetic head is cleaned (recording operation in the recording mode), no information is actually recorded during that time, and there is no need to delete unnecessary recorded information due to cleaning.

By arranging the optical pickup cleaning member in a silent section, it is possible to prevent a stop due to a reading error and the generation of noise noise.

By arranging the optical pickup cleaning member inside the area where the recording management information is recorded, the optical pickup can be already cleaned by the initial operation accompanying the loading into the disk drive, which is a troublesome operation. Becomes unnecessary. Since the optical pickup cleaning member is arranged at a place where the data density is low, a disc reading error hardly occurs. By disposing the optical pickup cleaning member at the position of the focus adjustment operation of the optical pickup, the optical pickup can be cleaned at the time of the initial focus adjustment operation. In the focus adjustment operation, since the optical pickup approaches the disk medium surface very close, the optical pickup cleaning member can be very short.

By appropriately adjusting the recording start position and / or the recording time of the unrecorded area, the cleaning operation is automatically terminated in a fixed time, so that the magnetic head can be prevented from being excessively cleaned, and the user can perform cleaning. Since it is not necessary to worry about time, operability is improved.
