DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to an information storage device using an exchangeable optical disk.

[0002]

2. Description of the Related Art In recent years, various types of information storage devices using media such as exchangeable optical disks and magnetic disks have been developed. For optical discs, music CDs, CD-ROs
In addition to those of the type that records off-the-shelf data, such as M, there are write-once optical disks that can be written only once and rewritable optical disks that can be rewritten any number of times, and are rapidly spreading.

[0003] In the above-mentioned ready-made disc, a title, a song name, and the like are usually printed on a label surface. On the other hand, write-once
In a rewritable disc, since the information written on the disc is determined by the user, nothing is described on the label surface about the disc contents. It is convenient if the file contents of the disc can be described on the label side or a picture can be printed by the user's hand. In addition, if an original label design can be applied to an existing disc, the applicability of the optical disc is expanded.

In response to such a demand, a printing apparatus capable of printing on the label surface of a write-once optical disc has been commercialized (hereinafter, referred to as a label printer). that is,
In other words, the printer is designed so that a thick and rigid printing medium called an optical disk can be inserted in place of the printer paper. The label printer is connected to a computer as one of peripheral devices.

[0005]

However, in the prior art, the label printer must be prepared separately from the optical disk device. For this reason, extra cost, space, and labor were required. Also, in order to actually print on the label surface of the optical disk, after confirming the contents of the disk using an optical disk device and a computer, remove the disk from the optical disk device, insert it again into the label printer, and perform printing. And the work was cumbersome. Further, it has been difficult to sequentially print while referring to the contents of the disk, or to add or change the print contents in parallel with addition or deletion of files.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an explanatory diagram showing an optical disk device according to one embodiment of the present invention.

The optical disk apparatus shown in FIG. 1 is an optical disk 1 on which information can be written and read optically. The optical disk is irradiated with a laser beam to change its optical properties to record information. An optical head 2 for reproducing information from light; a lead screw 14 and a feed motor 15 as optical head driving means 3 for moving the optical head 2 in the radial direction of the optical disk 1 and guiding the optical head 2 to a target track position A print head 4 for spraying ink onto a target point on the optical disk to perform printing, moving the print head in a radial direction of the optical disk, and guiding the print head to a print position on the optical disk by print head driving means 5. A certain lead screw 16 and a feed motor 17 are used to record and reproduce information on the optical disc. A spindle motor 6 for rotating an arbitrary point on the optical disc 1 in a tangential direction relative to the print head while rotating at a positive rotation speed, and a rotation axis of the spindle motor 6; A spindle 19 as a center, and a chucking section 2 as a detachable connection between the spindle and the optical disk.
0, a control circuit 7 for controlling the optical head 2, the optical head driving means 3, the print head 4, the print head driving means 5, and the spindle motor 6. The optical disc 1 has a recording surface 8 and a label surface 9. The optical head 2 faces the recording surface, and the print head 4 faces the label surface 9.

FIG. 2 is an explanatory diagram showing the configuration of the optical disc 1 of FIG. The optical disc 1 shown here has a recording surface 8 on which one side can record arbitrary information by a user, and a label surface 9 on which the other side can print character information or the like using ink. The center is provided with a center hole 10 for connecting to the spindle motor 6 of FIG.

FIG. 3 is a block diagram for explaining the operation of the information storage device according to the present invention. The optical disk device includes an optical disk 1, an optical head 2, an optical head driving unit 3, a print head 4, a print head driving unit 5, a spindle motor 6, and a control circuit 7. The optical disk device is connected to and controlled by the host computer 11. The overall operation status is indicated on the display 12.
To inform the operator.

In the optical disk device according to the present invention, information is recorded / recorded using an optical disk like the conventional optical disk device.
It has a function of printing character information on the optical disk while reproducing. Hereinafter, the operation of the optical disk device of the present invention when a user records arbitrary data on an optical disk and prints the title on the label surface of the optical disk will be described with reference to FIGS. 1, 2 and 3. I do.

The optical disk device has an optical disk 1 mounted thereon. When the optical disk device is accessed from the host computer 6, the control circuit 7 of the optical disk device operates the optical head driving means 3. The optical head is thereby moved toward a target track on the disk. On the other hand, the spindle motor 6 is controlled so that the rotation speed of the disk becomes an appropriate rotation speed according to the position of the optical head 2 on the disk. Next, the optical head 2 irradiates the optical disc 1 with a weak laser beam to read addresses and other information necessary for recording. After that, the optical disc 1 is irradiated with a strong laser beam to perform a recording operation.

Up to this point, there is no difference from the conventional optical disk device. However, the optical disc device of the present invention
Character information can be printed on the label surface 9 while the optical disk 1 is mounted on the optical disk device. Here, the operator starts the software for label surface recording. On this software, a print image combining a title to be recorded on the label surface, a print character for describing the file content, a picture to be inserted in the background, and the like is designed. When the print image is determined, the host computer 11 executes a print command. Then, the control circuit 7 of the optical disk device operates the print head driving means 5 to move the print head to a print position on the label surface of the optical disk. Thereafter, the print head 4 is controlled to start a printing operation.

The details of the printing operation will be described below. The print image created by the host computer is converted into a dot image of a polar coordinate display centered on the axis of the spindle. The print head 4 can be moved in the r direction of the disk by the print head driving means 5. The spindle motor 6 rotates the disk,
The print head 4 can relatively scan in the θ direction of the disk. By controlling the print head 4 to be driven while rotating the disk by combining the two operations, the print head 4 can freely scan the label surface 9 of the disk over the entire area.

When the print head 4 reaches a position where dots are to be hit, ink is sprayed onto the position to form minute dots. The ink is ejected in synchronization with the rotation of the disk using the index signal of the spindle motor 6. That is, once θ = 0 is defined at a certain position, the θ value can be obtained by counting the index signal. If the cycle of the index signal is too coarse for the control accuracy of the print head, it may be complemented using a PLL circuit or the like. By repeating the operation of moving the print head 4, rotating the optical disk 1, and ejecting ink at high speed, any image can be printed on the disk.

(Embodiment 2) FIG. 4 is an explanatory view showing an optical head drive unit and a print head drive unit of an optical disk apparatus according to another embodiment of the present invention.

The optical head driving means 3 and the print head driving means 5 in the first embodiment may be the same. The optical head 2 and the print head 4 of FIG. 4 are both mounted on a U-shaped carriage 13 and are positioned so as to sandwich the optical disk 1. When the optical disk 1 is mounted on the optical disk device, the optical head faces the recording surface 8 of the optical disk, and the print head faces the label surface 9. The carriage 13 can be moved in the radial direction of the disk by carriage driving means 24. The optical head 2 controls the recording surface 8 of the disk by controlling the spindle motor 6 together.
The print head can scan the label surface 9.
According to the present embodiment, since the optical head 2 and the print head 4 can be driven by one driving unit, the function equivalent to that of the first embodiment can be realized with a simpler configuration.

Since other details are the same as those of the optical disk device of the first embodiment, detailed description is omitted.

(Embodiment 3) The print head 4 of Embodiment 1
In the above control, the physical address of the recording surface 8 on the back surface may be used to obtain the θ coordinate of the print head. That is, the address of the recording surface 8 is read by the optical head 2. By taking into account the physical address and the positional relationship between the optical head 2 and the print head 4, the position of the print dot can be defined as an absolute position on the disk. In this case, since the position of the image printed on the label surface 9 is accurately correlated with the physical address of the recording surface 8, there is an advantage that the addition or rewriting of the print content can be performed without positional deviation. At this time, since the data of the printing position can be left on the recording surface 8 of the disk together with the contents of the printing, if software corresponding to the printing is prepared, it is convenient to rewrite the label.

In this case, if the speed performance of the print head 4 is sufficient, the recording /
Printing may be performed with the rotation speed at the time of reproduction.

Since other details are the same as those of the optical disk device of the first embodiment, detailed description and drawings are omitted.

(Embodiment 4) The print head 4 of Embodiment 1
In the control of the spindle motor 6, the control may be such that the spindle motor 6 rotates at a constant speed at the same time as the printing operation is started. In this case, the rotation angle of the disk can be calculated based on the rotation waiting time without monitoring with an index signal or the like. Therefore, the same printing operation as in the first embodiment can be performed by managing the ink ejection timing of the print head by time.
The number of rotations of the disk at the time of printing depends on the print head 4
May be determined according to the printing speed performance. According to the present embodiment, printing can be performed on the label surface 9 with a simpler control circuit.

Since other details are the same as those of the optical disk device of the first embodiment, detailed description and drawings are omitted.

(Embodiment 5) The print head 4 of Embodiment 1
In the control of the spindle motor 6, during the printing operation, the spindle motor 6 may be controlled to accelerate or decelerate according to a printing pattern. That is, a portion where the print pattern is dense or dark may be rotated slowly, and a portion where the print pattern is coarse or thin may be rotated quickly. By scanning the print pattern at the optimum speed, a clearer image can be printed in the shortest time. In this case, the rotation angle of the disk may be obtained from the index signal, the physical address of the recording surface, or the like.

Since other details are the same as those of the optical disk device of the first embodiment, detailed description and drawings are omitted.

(Embodiment 6) The print head 4 of Embodiment 1
In the control of the spindle motor 6, during the printing operation, the spindle motor 6 may be controlled to accelerate or decelerate according to the radial position of the print head on the disk. That is, the CL is adjusted so that the linear velocity at the position where the print head 4 intends to print becomes constant.
V control may be performed. Thereby, printing can be performed with uniform quality on the inner and outer circumferences.

The other details are the same as those of the optical disk apparatus of the first embodiment, so that detailed description and drawings are omitted.

(Embodiment 7) The print head 4 of Embodiment 6
In the control of the spindle motor 6, the print head 4 and the optical head 2 may be moved synchronously in the radial direction during a printing operation. Thus, since the CLV control can be performed using the signal of the recording surface 8 of the disk, the same function as that of the sixth embodiment can be realized more easily.

Since other details are the same as those of the optical disk apparatus of the first embodiment, detailed description and drawings are omitted.

In this embodiment, the optical disk 1 shown in FIG. 2 can be printed on a label on a cartridge even if the optical disk 1 is contained in a cartridge or the like.

According to this embodiment, since the print head 4 can be controlled by a simpler method, the control circuit 7 can have a simple configuration.
