- the continuous control track 60 having a fine pit or a fine wobble groove force and having a configuration in which the fine flow path and the control track are formed without overlapping, the control when performing a reaction or the like is performed. Since the centrifugal force can be applied while referring to the truck 60, there is an effect that the reaction and the like can be controlled under certain conditions. In addition, there is an effect that the centrifugal force can be changed according to the reaction process.
- the optical disk device is used by mounting the optical disk device.
- the present invention is not limited to this.
- the present invention is applied to a magnetic disk device such as a floppy (registered trademark) disk.
- the control track 60 may be constituted by a magnetic medium and a recording signal force such as a magnetic pattern force so that the control track 60 can be read by a magnetic head.
- the embodiments of the present invention have been described above. In addition, various modifications are possible in accordance with the gist of the present invention. Also, the components described in the description do not disturb the invention. May be interchanged within a certain range. Further, the No. 1 chemical chips 1 to 5 may be mounted inside a circular or rectangular parallelepiped cartridge. Further, the signals recorded on the control track 60 are (1, 7), (1, 8), (1, 9), (1, 10), (1, 11) in addition to the (2, 10) code. ), (2, 7), (2, 11) codes, etc. can also be used.
