TECHNICAL FIELD OF THE INVENTION
The present invention is an information recording medium that records information by rotating a disk to change the state of the disk surface and its vicinity, and reads information by detecting a change in the state of the disk surface and its vicinity, such as light or The present invention relates to an information recording apparatus using an optical disk, a magneto-optical disk, or the like, which is an information recording medium using magnetism or using light and magnetism. In particular, except for recording / reproducing information while rotating a medium such as an optical disk. The present invention relates to an information recording apparatus using an information recording medium capable of recording / reproducing information. The present invention can be similarly applied to any disk-shaped recording media.
[0002]
[Prior art]
In recent years, optical disks have been widely and generally used as information recording means. Conventionally, in the case of optical disks that have been exclusively used for reproduction, new disk media such as a CD-R that allows users to record / reproduce their own information and a rewritable CD-RW have become widespread.
[0003]
These media are disks provided with a circular hole having a diameter of about 2 cm at the center, and recording / reproduction is performed by rotating the disk. Unlike a conventional MO, there is no case where a disk medium is stored.
[0004]
Further, by attaching an IC memory or the like to a case for storing a disk medium, data necessary for file management such as a file name and a recording date and time recorded on the medium is stored in the IC memory, and an information management function is improved. there were. This is not limited to a disk medium, but can be easily realized by providing an IC memory in a case where a medium is stored, such as a video tape, for example.
[0005]
On the other hand, it is easily conceivable that the same function can be realized by attaching an IC memory to a medium body of a disk medium having no case for storing the medium, such as a CD-R or a CD-RW. In the case of CDs and CD-RWs, since a disk is rotated at a high speed, simply installing an IC memory causes a problem.
[0006]
Examples of an optical disk provided with an IC memory include (1) "information recording medium and storage device thereof" disclosed in JP-A-5-109236, and "2" disclosed in JP-A-5-73735. There is a storage medium.
[0007]
An object of the invention of the above (1) is to provide an information recording medium capable of easily selecting a medium and storing necessary bibliographic items, and a storage device therefor. The configuration is such that, in an information recording medium for recording / reproducing information using light and / or magnetism, a storage device using an IC memory is provided in a main body of the medium or a case for holding the medium, and the recording medium is recorded on the medium. An information recording medium characterized in that bibliographic items related to the information are stored. Further, the present invention provides an apparatus for storing the information recording medium, wherein at least a part of the part holding the medium has a terminal for reading the contents of an IC memory provided in the medium. Is provided.
[0008]
An object of the invention (2) is to read necessary information such as a file name, a revision, and a date from a semiconductor memory and display the information on a liquid crystal display on a storage medium. The configuration is such that data can be written and read from the information processing device to and from the semiconductor memory backed up by the data storage battery, and the data storage device is mounted on a card-shaped container that can be mounted on the information processing device. A storage medium containing a battery and the semiconductor memory, comprising: a liquid crystal display; and a display control circuit for reading a file name or the like from the semiconductor memory and displaying the file name on the liquid crystal display. It is.
[0009]
However, the basic configuration of the present invention according to the above (1) and (2) is based on the premise that the IC memory is installed in a case or cartridge that stores the optical disk main body, and the optical disk main body that needs to be rotated needs to be rotated. This does not take into account the installation of an IC memory or the like.
[0010]
In addition, an IC memory or the like attached to the medium body cannot read / write information in parallel with reading / writing information while rotating the medium.
[0011]
[Problems to be solved by the invention]
The present invention has been made in view of the above-mentioned problems of the related art, and has as its object to record / reproduce information on / from an information recording medium (media) such as an optical disk while rotating the information recording medium. It is another object of the present invention to provide an information recording apparatus capable of performing recording / reproduction on an IC memory or the like attached to the information recording medium while the information recording medium is stationary.

A disc-shaped information recording medium 101 such as an optical disc has a circular hole 104 concentric with the center 105 of the disc, and is an information recording medium that inputs and outputs information while rotating the disc with the center 105 of the disc as the center of rotation. is there. In the information recording medium shown in FIG. 1, an information recording area 102 for inputting / outputting information accompanied by rotation of a disk and an area 103 in which input / output of information accompanied by rotation of a disk is difficult are provided inside the information recording area 102. In this area 103, four IC memories 106, 107, 108 and 109 capable of inputting and outputting electrical information in a stationary state without rotating the disk are arranged.
[0018]
Among these four IC memories, the IC memory 106 disposed above the disk center 105 and the IC memory 107 disposed below the disk center 105 are point-symmetric with respect to the disk center 105. Similarly, the IC memories 108 and 109 arranged on the left and right of the center 105 of the disk are also point-symmetric with respect to the center 105 of the disk. Further, these four IC memories are arranged at the same angular pitch (90 °). With such an arrangement, the influence of the arrangement of the IC memory at a position deviated from the rotation center on the disk rotation, for example, the influence of eccentricity or the like is prevented.

[0020]
FIG. 3 is a schematic front view showing a state where the information recording medium 201 incorporated in the information recording apparatus is being driven to rotate. At this time, the terminals 204 and 205 that have been in contact with the IC memories 202 and 203 move upward and are separated from these IC memories, and do not hinder the rotation of the information recording medium 201. Further, the recording / reproducing head 207 approaches the disk surface (the surface of the information recording medium 201), and performs the reading / writing operation of the information recorded on the disk. This information is information sent from the information control device 208 or the like in the information recording device. At the same time, information related to this information, such as information required for file management, which is read while the disc is not rotating, is sent from the information control unit 208 to the temporary storage unit 206 and stored.
[0021]
When the recording / reproduction by rotating the information recording medium 201 is completed and the rotation of the information recording medium 201 stops, the terminals 204 and 205 come into contact with the IC memory of the information recording medium again (FIG. 4), and the temporary storage means 206 Is stored in the IC memory.
