Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a disc-shaped recording medium (hereinafter referred to as a disc).
The present invention relates to an information recording and reproducing apparatus that records information on a surface and reproduces the recorded information.

[Conventional technology]

With the development of today's electronics, information recording and reproducing devices that can randomly record, reproduce, or erase audio or image information with high performance using a light beam such as Rede light have been commercialized. For example, in an optical video disk device, an optical head detects the protrusion (pit) turn on the surface of a disk-shaped recording medium made of transparent acrylic resin, etc. as a digital quantity, converts it photoelectrically, and then converts it into an appropriate amount using an amplifier. After adjusting the gain and converting the signal into a predetermined analog value via a reproducing circuit such as a DA converter, the signal is output to an output device such as a speaker or a CRT. In this way, the desired sound or color image can be obtained instantaneously and with high performance.

Although the information recording/reproducing apparatus exemplified above has high performance and high quality, its operability is behind the above-mentioned performance. In other words, conventional disk loading/unloading operations generally involve two methods: using a single disk (disk method) and using a cartridge with a disk inside (cartridge method).
The information recording/reproducing device was classified into two types, and the mounting/detachment mechanism of the information recording/reproducing device had a different structure to match these formations. However, in one device, only one of the disk method and the cartridge method can be selected, and in reality, two information recording and reproducing devices are installed so that they can support both the disk method and the cartridge method. The disks or cartridges are sorted over time, and the disks or cartridges are loaded and unloaded into the respective devices. This requires a huge amount of time and effort, and it is not possible to respond appropriately and efficiently to the increasing number of IJs (discs or cards) used as recording media due to today's increasing amount of information, in terms of ease of search and installation/detachment. was occurring.

FIG. 8 is a perspective view showing the structure of a conventional disc type information recording/reproducing apparatus. The disc 2 is directly fixed in the groove 5a of a predetermined capacity of the disc mounting member 5, and the information recording/reproducing device 30alC is mounted and removed by moving the guide rail 4 to s-s' as shown.

FIG. 9 is a perspective view showing the structure of a conventional IJ horn type information recording and reproducing apparatus. The two-disk cartridge 1 is installed and protected in advance, and after the cartridge 1 is fixed at a predetermined position on the guide rail 4, the information is transferred by moving the guide rail 4 in the s-s' direction shown in the figure. When the cartridge and disk systems are used as described above, two different types of devices are required, which requires a large amount of cost. In addition, it causes inconvenience for the operator when searching, loading and unloading operations.Therefore, by providing one or more loading and unloading ports in one information recording and reproducing device, it is possible to load and unload the device while it is fixed. The direction can be taken in one or more directions, and the car)
There has been a strong desire to develop a compatible information recording and reproducing device that can be used for both IJ and disc systems.

They are adapted to be closely engaged with each other. In the above components, the same number of each element (for example, 4 in the case of the fixed bin 66) are provided at symmetrical positions in the sliding direction u,..., 7J/, and each element is integrated to form a disk mounting table. It is designed to operate smoothly.

The mounting function of these configurations will be explained.

The mounting direction is the U direction, and currently the disk mounting table 10a
A desired disc is placed on the disc and is about to be fed to a predetermined optical information detection position of the information recording and reproducing apparatus. In this state, as the motor 61 rotates in one direction, the gear 6
