Description

Bio disc {Bio disc}

The present invention relates to a bio-disc, and more particularly, to a bio-disc usable for an existing optical disc drive.

As we move into an aging society, there is a growing interest in health and the cost of disease diagnosis and treatment is rapidly increasing. In the case of diseases that are difficult to treat, the early detection by early detection is important because the survival rate can be increased and live for a long time. However, patients usually have to be aware of the symptoms before they visit the hospital, so early detection is not easy, and even in the case of compulsory comprehensive examinations, the examination cycle is not short, so early detection of the disease is limited.

Thus, self-diagnosis kits for easy diagnosis of individuals at home are being developed for early detection of high disease, and bio-disc for diagnosing major diseases such as cancer and diabetes has been introduced. Bio-disc is advantageous in terms of cost because the optical drive device can be used as an analyzer and manufacturing is similar to that of the conventional optical disc.

However, the bio-disc currently being researched or introduced as a patent is often incompatible with the conventional optical drive, and there is a problem in that it does not properly utilize these advantages.

Accordingly, the present invention was created to solve the above problems, and an object of the present invention is to provide a bio-disc that can be used without changing the optical drive.

In addition, another object of the present invention is to provide a bio-disc capable of storing and delivering the diagnostic results.

The present invention has been made to achieve the above object, the bio-disc according to an embodiment of the present invention, the diagnostic region including a diagnostic kit for causing a pattern change in response to biochemicals; And a recordable data area for storing a diagnosis result.

In one embodiment of the present invention, the data area is located inside and the diagnostic area is located on the outer periphery more than the data area, or the diagnostic area is located inside and the data area is located on the outer periphery than the diagnosis area. Can be.

In addition, in an embodiment of the present invention, the disk including only the diagnostic area and the disk including only the data area may be separated, and may be combined and separated by using protrusions and grooves in the cross section of each disk.

Further, in one embodiment of the present invention, disc information indicating that the bio disc is recorded in the lead-in area, which may be recorded in physical format information in the ADIP or embossing area of the lead-in area, and the disc information may be recorded in the diagnosis. The apparatus may further include information indicating the type of diagnostic kit included in the region. In another embodiment, disc information indicating that the disc is a bio disc may be recorded in an outer area of 8 cm or more.

In addition, in one embodiment of the present invention, the device for reading the changed pattern of the diagnostic kit and may include position information for measuring the relative position of the pattern, the circumferential position information, the inner or outer circumference that the device does not touch Regions having different reflectances in the circumferential direction may be alternately arranged in the region, and thus may be detected through the LED light emitting element and the light receiving element positioned in the inner circumferential or outer circumferential region not reachable to the apparatus.

In addition, the radial position information may be located from the inner circumference to the outer circumference of the diagnostic area, the neighboring radius and the pattern located at a predetermined distance may be different from each other, and the predetermined width may be maintained in the circumferential direction. Can be detected by a reading device.

Therefore, the system can be compatible with existing optical drive systems, thereby realizing a low cost, and can be manufactured and used with minimal changes to firmware or components of the existing optical drive, and can be used with existing optical disks. In addition, the bio-disc according to the present invention has both a recording area and a diagnosis area, so that diagnostic results can be stored, and in the case of a removable disk, the bio-disc can discard the diagnosis area after diagnosis.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The bio-disc to which the present invention is applied may include a diagnostic area for reacting with a substance separated from the body and a data area for recording a reaction result. In addition, the bio-disc system to which the present invention is applied is diagnosed by, for example, separating blood while rotating the bio-disc injected with blood at high speed, and reading the pattern in which the separated blood (serum) reacts with the diagnostic kit in the disc. It is a system capable of obtaining a result and optionally recording the diagnosis result in a data area provided in the bio disc.

1 shows the structure of a bio-disc according to the present invention.

The inside of the disc has an existing optical disc structure of 8 cm that can be recorded or rewritten, and has a diagnostic area (channel, valve, diagnostic reagent storage, etc.) for the diagnostic test between 8 cm and 12 cm. The 8 cm inside contains a data area for storing diagnostic results. Disc types such as CD-R, CD-RW, DVD-R, DVD + R, DVD-RW, DVD + RW, DVD-RAM, BD-R, etc. The structure may vary.

In addition, as shown in FIG. 2, it may be considered that there is a diagnostic area in the inner periphery, a data recording area in the outer periphery, or only a diagnostic area, depending on the diagnostic content. In this case, there is a problem in compatibility with an existing optical drive. It may be present, but it can be applied to a stand-alone disk reader.

The disk proposed in FIGS. 1 and 2 is an integrated type, but as shown in FIG. 3, a detachable disk in which a conventional 8cm optical disk and a donut-shaped biodiagnostic region of 8cm to 12cm size are separated is possible.

Depending on the diagnostic content, the storage temperature of the diagnostic reagent may vary from -20 degrees Celsius to room temperature, which may require refrigeration and also the structure of the detachable bio-disc may be necessary because the method of making the diagnostic disc may be different from the conventional optical disc. have. As shown in FIG. 4, such a disk can be assembled / separated by fitting using projections and grooves in the disk section, for example, by using a lens or a main body of an interchangeable lens camera or by using additional components. It is possible to combine or separate two discs, an optical disc for recording and a disc having a diagnostic channel.

Such a removable disk can be conceived in such a way that, like the film of a disposable camera, after removing the unnecessary diagnostic channel part after diagnosis or reusing the diagnostic channel, the inner 8 cm media can be assembled and used.

The size of the bio-disc according to the present invention may vary depending on the diagnostic content, and the size of the internal disk including the recording area may also vary according to the contents of the diagnostic content. It is advantageous that the size of the disc does not exceed 12cm in order to apply to the existing optical drive, but a disc larger than 12cm may be considered when using a stand-alone drive that does not consider the compatibility with the existing optical drive. In addition, if the amount of diagnostic content is small and portability is important, it may be possible to make the overall size smaller than 8 cm.

In order to recognize a disk loaded with an existing disk drive as a bio disk, disk information indicating that the bio disk must exist inside, and the storage method thereof can be the following method.

First of all, it is stored in the lead-in area of 8 cm inside.

Conventional optical discs store information about their discs in ADIP (Adress In Pre-groove) or in the embossing area of the lead-in area. The disc drive uses this information to recognize the disc details. It performs internal servo and setting operation suitable for this.

As shown in Fig. 5, the bio-disc according to the present invention can put its own information into the ADIP or lead-in area of the internal 8 cm disc. When the internal 8 cm disc is DVDR / + R, version information according to the bio disc type or the diagnosis type may be stored in the physical format information in the embossed area or the ADIP area of the lead-in area, respectively. In addition, the information of the bio-disc may be stored in another form in the reserved area for compatibility with the existing optical disc lead-in structure.

In the example of FIG. 5, if the bookmark type of the first byte of the physical format information of the DVD-R / -RW is '0100b', it indicates the DVD-Bioo disc, and if the compatible part version is '0001b', the cancer diagnosis is performed. , '0010b' indicates diabetes diagnosis, and '0100b' indicates DNA extraction.

Next, a method of securing an area for storing bio-disk information outside the outer 8cm disc is provided.

As shown in FIG. 6, in order not to change the size of the internal 8cm optical disc, disc information indicating that the biodisc is inserted into the outer region after 8cm may be inserted. This structure has the advantage of being able to manufacture without changing the specification of the existing 8cm disc. This structure is a structure that can be used in the form of a detachable bio disc.

In the example of FIG. 6, the disc information may include bio disc identification information indicating the type of the disc and version information indicating the type of the diagnostic channel. In the version information, '0001b' indicates cancer diagnosis, '0010b' indicates diabetes diagnosis, and '0100b' indicates DNA extraction. In this case, when there are several versions of the diagnostic channel on a disk, for example, the cancer diagnosis channel and diabetes diagnosis channel, the version information may be '0011b'.

There may be several channels on the circumference of the bio-disc, ie the various channels for diagnosing various diseases, or the same channels may be arranged repeatedly. Alternatively, even in one channel, the pattern according to the examination result may be distributed over a large angle in the circumferential direction or in a plane over a wide radius. Therefore, in order for the optical pickup to scan the examination result pattern, it is necessary to confirm the relative position between the optical pickup and the pattern, that is, the position in the circumferential direction and the position in the radial (radial) direction.

In order for the pickup to accurately measure the diagnostic results of the bio-disc, precise position control of the pickup and spindle motor is required. To this end, as shown in FIG. 7, the bio-disc can record the circumferential position information of the disc and read it through the LED light emitting element and the light receiving element. As shown in FIG. 7, circumferential position information may be represented by alternately arranging a region having a high reflectance and a region having a low reflectivity in the circumferential direction.

In consideration of compatibility with the existing optical drive standard, the position information may be recorded in the area where the pickup does not reach inside the lead-in, or may be recorded at the outermost circumference, or recorded in the circumferential direction next to the diagnostic area to increase accuracy. You may.

In addition, since there may not be a data track for the tracking servo in the bio-disc, it is not easy to check the position in the radial direction when scanning the examination result pattern. The radial step position of the pick-up can only be determined indirectly through the rotational step amount of the sled motor.

Therefore, in the present invention, as shown in Fig. 8, the radial position information is recorded in the radial direction between the diagnostic regions, wherein the radial position information is circumferentially arranged by a predetermined position through the actuator and the sled motor for the pickup servo. The positional information patterns at neighboring radii are different from each other so that they can be moved to each other, but the positional information patterns are circumferentially arranged in a circumferential direction so as to recognize the radial positional information at a predetermined radius of the rotating disk. Can record

The pickup scans the diagnosis result pattern in the concentric circle of the current radius, and then moves the objective lens to the next radius after a predetermined distance (d) to scan the diagnosis result in the concentric circle of the corresponding radius. You can see if you have moved by the distance.

The accuracy of such circumferential position information or radius position information is determined according to the resolution of the examination result pattern. If the examination result pattern requires precision, such a location information pattern should also be dense. If the examination result pattern is not so precise, the location information pattern may be spattered accordingly.

9 illustrates a method for measuring a bio disc diagnostic channel with a pickup of an optical drive. The light output from the laser diode (LD) enters the diagnostic channel with the reflective surface of the disk through the objective lens and the reflected light enters the photo detector (PD).

FIG. 10 illustrates an electrical signal when the light reflected by the measuring method of FIG. 9 is read by the PD, and detects and reflects the degree of the reflection or absorption due to the changed color of the diagnostic channel through the PD. This method may be continuous or on / off data depending on the type of diagnostic reagent or diagnostic channel (type of diagnostic content).

9 illustrates a case where the diagnostic result is measured through an optical pickup in which data is written to or read from the optical disk, the diagnostic result pattern may be read through a scan means separate from the optical pickup. In this case, the scanning means can be mounted on the opposite side where the optical pickup is located in order to avoid collision with the optical pickup.

In addition, the scanning means provided separately from the optical pickup may be implemented in a reflective type such as an optical pickup, that is, a light source emitting a beam and a detector for detecting a beam reflected from a diagnostic result pattern. Unlike the optical pickup, it may be implemented in a transmissive type, that is, a light source and a detection unit are separated above and below the disk.

When there is a scanning means separate from the optical pickup, two or more laser diodes or LEDs of different wavelengths may be used as the light source of the scanning means, and a CCD or a CMOS sensor or the like may be used as the detection unit of the scanning means, and the diagnostic result pattern may be used. It is also possible to detect a change in color appearing on the screen.
