[0020]

As described above, in a hybrid card provided with a non-contact IC and an optical recording section, the non-contact IC, the antenna coil, and a part of the optical recording section are arranged so as to overlap each other. I have.

By the way, it is possible to change the size of the optical recording section and arrange the non-contact IC and the antenna coil and the optical recording section in advance so as not to overlap.

As one of the methods, it is conceivable to change the size of the recording medium to be applied or adhered to the substrate.

However, if the size of the silver halide film as the recording medium or the size of the area to which the dye is applied is changed, the manufacturing process such as the change of the cutting process for the silver halide film, the change of the coating machine for the dye, etc. And the production line must be changed, which increases the production cost.

Therefore, it is possible to manufacture without using a conventional manufacturing process or manufacturing line without increasing the cost, and it is possible to provide a hybrid card at relatively low cost.

For this reason, in such a hybrid card in which the non-contact IC and the antenna coil and a part of the optical recording unit overlap each other as in the conventional example, the optical recording unit overlapping the non-contact IC and the antenna coil is used. When recording and reproducing information, the optical pickup and the antenna coil are aligned on a straight line in the thickness direction of the card, and the following new problem occurs.

(1) Since the recording / reproducing operation of the information of the AT / AF actuator and the non-contact IC of the optical pickup uses the change of the magnetic field, the change of the magnetic field affects each other.

For example, if the AT / AF actuator is affected by the information recording / reproducing operation of the non-contact IC,
When the light spot is not focused on the optical recording surface,
The recording / reproduction of information to / from the optical recording unit becomes unstable, for example, the control malfunctions and deviates from the target information track, and the reliability of the device is significantly impaired.

(2) Similarly, when the operation of the AT / AF actuator affects the recording / reproducing operation of the information of the non-contact IC, the recording / reproduction of the information to / from the non-contact IC becomes unstable, and the worst case In such a case, there is a possibility that a situation such as loss of information recorded in the IC unit is caused.

As another method, a transparent substrate of a hybrid card is prepared so that an optical recording unit other than the non-contact IC and the antenna coil is located in the size or the installation position of the non-contact IC and the antenna coil in the hybrid card. A method is conceivable.

However, in order to change the size and position of the optical recording section, a master for producing the above transparent substrate is required.
(Type) must be newly created. Non-contact I
Since the shape and arrangement of the C and the antenna coil can naturally be considered variously depending on the purpose, function, and the like, it is necessary to form a mold for forming a transparent substrate for each of them, resulting in a significant increase in cost. Would. Furthermore, storing and managing a plurality of molds imposes a burden on the manufacturer on management, and inevitably complicates work and management and increases costs. In addition to this, in the production line, depending on the type of hybrid card to be produced, it is necessary to perform the work of removing and attaching the mold for producing the transparent substrate, which increases the work time, speeding up the production line, This has a negative effect on cost reduction.

As described above, in order to arrange the optical recording unit, the non-contact IC, and the antenna coil in the hybrid card so as not to overlap, many problems as described above occur.

The present invention is free from such problems.
Therefore, there is provided an information recording / reproducing system capable of controlling a hybrid card provided at low cost without malfunction without changing a conventional manufacturing line, and without causing a change in a mold and an increase in manufacturing cost due to the change. The purpose is to:

In one aspect of the present invention, the access prohibited area is set in a predetermined portion of an optical recording section of the hybrid card, preferably in an information track near an end of an information recording track group provided on the card. More preferably, the setting is made based on information additionally written on the plurality of information tracks. The information additionally written on the plurality of information tracks may be the same information.

In particular, the information additionally recorded on the hybrid card may be a track number or a track number and area identification information. It is preferable that the determination as to whether or not the area determined by the track number is the access prohibited area is made based on the area determination information, and the area determination information is preferably binary information.

On the other hand, it is possible to provide a highly reliable hybrid card recording / reproducing system which always performs stable recording / reproducing.

Further, by setting the access prohibited area based on the information added to the hybrid card, the non-contact IC is created when the hybrid card is created.

Also, depending on the type of hybrid card,
Since information for setting the effective optical recording unit can be provided for each card, one information recording / reproducing apparatus can support various hybrid cards.

Further, even if there are plural types of hybrid cards, the type for producing a transparent substrate having an optical recording section is such that the optical recording section as shown in the conventional example is arranged so as to overlap the non-contact IC and the antenna coil. What is needed is only one type. As a result, not only can the production line or the production process be complicated and cost increase can be avoided, but also a single type of mold can handle a plurality of hybrid cards, thereby achieving a significant cost reduction in the production of hybrid cards. be able to.

Embodiments of the present invention will be described below in detail with reference to the drawings. The configuration of the information recording / reproducing apparatus used in the present invention is the same as that shown in FIG. 6, and the hybrid medium shown in FIG. 2 is used as a recording medium.

FIG. 1 is a flowchart showing the operation procedure when a card is inserted. The processing and the control and management of each unit of the apparatus shown in FIG. 1 are performed by the CPU and the MPU of the recording and reproducing apparatus.

Next, with reference to FIG. 1, FIG. 2, FIG. 4, FIG. 5, and FIG.

First, as shown in FIG. 6, when the hybrid card C is inserted into the insertion slot 6 of the drive 1, the MPU
Reference numeral 3 controls each unit to convey the hybrid card C to a predetermined position in the apparatus, irradiates a light spot to the home position 3 in FIG. 5, and performs an AF pull-in operation here. At this time, the CPU 2 detects the presence or absence of the optical recording section in the card conveyed into the apparatus, depending on whether the AF pull-in operation is normally completed (S2).

On the other hand, when the hybrid card C is transported to a predetermined position in the apparatus, the non-contact IC head 110 faces the antenna coil 102 connected to the IC chip 101 of the hybrid card C in a substantially close contact state. I
Recording and reproduction with respect to C become possible.

Here, the CPU 2 detects the presence or absence of the non-contact IC part in the card conveyed into the apparatus by performing the information reproduction or the recording operation for the predetermined address, and determining whether or not the result is completed normally. S3 and S
3 ').

By these series of operations, it is determined whether or not the card conveyed into the apparatus is the hybrid card shown in FIG.

When it is determined that the hybrid card is a hybrid card (S4), based on the information recorded in the ROM of the MPU 3, it overlaps with the antenna coil 102 fixedly arranged at a predetermined position of the hybrid card C as shown in FIG. The set optical recording unit 103a is set as an access prohibited area (S8). The information recorded in the ROM includes the number of usable information tracks, the track number of the information track that does not overlap with the antenna coil and is closest to the antenna coil, and the like.

Accordingly, in the case of a hybrid card, the recording of information in the optical recording section by the optical head and / or the reproduction of information from the optical recording section are indicated by hatching in FIG.
This is performed in the optical recording unit 103b other than the optical recording unit 103a that overlaps the antenna coil.

FIG. 4 shows the optical recording unit side of the hybrid card, and is a diagram defining an access-prohibited area and an accessible area of the optical recording unit shown in FIG. 2B.

Thereafter, in the case of the hybrid card, information recording and reproduction are performed on the optical recording section and the non-contact IC section in the same manner as in the conventional example.

When it is determined that the card is an optical card (S
5) recording information on an optical recording unit by an optical head or /
Reproduction of information from the optical recording section is performed on the entire optical recording section in the same manner as in the conventional example.

If it is determined that the card is a non-contact IC card (S6), the non-contact IC card is processed in the same manner as in the conventional example.
Recording / reproduction of information to / from the unit is performed.

As described above, since the embodiment of the present invention includes the card discriminating means, the recording medium such as an optical card or a non-contact IC card is not limited to a hybrid card, but is capable of transmitting information to a single card. Recording and reproduction can be performed.

When an optical card having only an optical recording section is inserted, the entire optical recording section can be used.
The memory capacity of the optical card can be maximized.

In the embodiment of the present invention, the card is determined by detecting the presence or absence of the optical recording unit and the non-contact IC unit. However, the information preformatted in the optical recording unit or the IC chip The card determination may be performed based on the recorded information. In any case, the card can be identified simply by accessing one type of recording medium.
The card type can be determined relatively quickly.

In the embodiment of the present invention, M
The access prohibition area of the optical recording unit is set based on information recorded in advance in the PU, but the optical recording unit is pre-formatted in the optical recording unit on the card side or based on information recorded in the IC chip. An access prohibited area may be set. In any case, the access prohibition area of the optical recording unit can be set without performing the card discrimination, so that the operation can be shifted to the information recording / reproducing operation relatively quickly. Furthermore, since information on the access area of the optical recording unit is obtained from the card, it is possible to cope with a hybrid card having a different shape of the antenna coil and the optical recording unit, and always effectively utilize the memory capacity of the optical recording unit. it can.

Next, after the hybrid card is created, a valid optical recording section is set based on the information additionally recorded in the recording section of the hybrid card when the card is issued, for example, and the optical recording is performed on the valid optical recording section. An information recording / reproducing system according to the present invention which can record or reproduce information on a unit will be described.

FIG. 9 shows a hybrid card provided with an area 120 for additionally writing information for setting an effective optical recording section. FIG. 9A shows the hybrid card from the non-contact IC 101 side. FIG.
03 is indicated by a dotted line. FIG. 9B is a view of the hybrid card viewed from the optical recording unit 103 side, and shows a non-contact IC.
101 and the antenna coil 102 are indicated by dotted lines.
The additional information is written to the hatched area 120 in the figure near the end of the information recording track group of the optical recording section.

Next, the contents of additional recording information for setting an effective optical recording section will be described. First, the structure of the additional recording information is information indicating an effective optical recording area. Information for setting an effective optical recording unit includes, for example, the non-contact IC 10
1 or two track numbers at both ends of an area where the antenna coil 102 and the optical recording section 103 overlap, or two track numbers at both ends of an area where the antenna coil 102 and the optical recording section 103 do not overlap.

FIG. 10 is a view showing an effective optical recording section 103b (hatched section) set based on the additional information. An access method to the optical recording unit of the information recording / reproducing apparatus based on such additional information of the hybrid card will be described.

First, as shown in FIG. 6, when the hybrid card C is inserted into the insertion slot 6 of the drive 1, the MPU
Reference numeral 3 controls each unit to convey the hybrid card C to a predetermined position in the apparatus, irradiates the home position 3 in FIG. 4 with a light spot, and performs an AF pull-in operation. Next, it moves to the additional information recording unit 120 on the hybrid card and reproduces the additional information.

From the reproduced information, track number information for setting an effective optical recording section is obtained. The area between the two track numbers at both ends of the area where the obtained IC chip 101 and antenna coil 102 and the optical recording section overlap each other is set as an access prohibited area, and access is made to an area other than the access prohibited area. The recording or reproduction of information is performed. Of course, the information for setting the effective optical recording unit may be a track number of an area where the IC chip 101 or the antenna coil 102 and the optical recording unit 103 do not overlap. Whichever you choose, the same effect is obtained. However, whether or not the track number to be added indicates an overlapping part must be determined in advance on the system. Note that it is also possible to provide the additional recording information with area discrimination information (for example, binary information) indicating whether or not the track number of the additional recording information is the above-mentioned overlapping portion. It is possible to accurately record and reproduce information on the optical recording section only with the information.

Further, the same additional information may be recorded on a plurality of information recording tracks near the end of the information recording track group of the optical recording section. Thus, even if the reproduction of the information recording track accessed first fails, it is possible to accurately record or reproduce information on the optical recording unit by accessing the next information recording track. Since the information recording track group of the optical recording unit is composed of thousands of tracks, the number of information recording tracks for recording additional recording information is 5 to 5.
It suffices to secure about ten, so that the decrease in the total recording capacity can be suppressed to 1% or less, and the effect on the system is at a level without any problem.

Next, a method of setting the second access prohibited area by additional writing will be described. That is, this is a method in which card type discrimination information indicating that the card is a hybrid card is added to a part of the optical recording unit, and an access prohibited area is set based on the information.

For example, binary information is added, and if it is "1", it is recognized that the card is a hybrid card, and the access prohibition area is set in the information recording / reproducing apparatus by a track number set as a default value in advance. The form of the additional information is not limited as long as it is promised between the hybrid card and the information recording / reproducing device.

[0075]

As described above, according to the information recording / reproducing system of the present invention, when a card for recording / reproducing information is a hybrid card, recording / reproducing of information to / from an optical recording unit by an optical head is performed. And / or reproduction of information from the optical recording unit is performed only on the optical recording unit other than the optical recording unit overlapping the antenna coil connected to the IC. For this reason, the optical pickup and the antenna coil do not line up in a straight line in the thickness direction of the card, which adversely affects the recording and reproduction of information of the non-contact IC, and the loss of information recorded in the IC section. Can be prevented beforehand.
This makes it possible to provide a highly reliable hybrid card recording / reproducing system that constantly performs stable recording / reproducing on any recording medium of a hybrid card including an optical recording unit and a non-contact IC unit.

After the hybrid card is created, for example, in a hybrid card in which information for setting an effective optical recording section is added to a predetermined portion of the optical recording section, the non-contact IC and the antenna coil are reproduced by reproducing the added information. Since information can be recorded or reproduced on an optical recording portion other than the portion where the optical recording portion and the optical recording portion overlap, the AT / AF
The actuator can more stably record or reproduce information on the optical recording section without being affected by the magnetic field generated by the IC recording and reproducing apparatus.

Further, from the viewpoint of manufacturing a hybrid card, it is not necessary to use a mold for forming an optical recording unit in accordance with various hybrid cards, and a great cost reduction can be achieved in card manufacturing. It is also possible to speed up card creation.
