Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording and recording method for ejecting a recording medium held by a holder by an ejecting means to record an information signal on the recording medium and / or reproducing the information signal recorded on the recording medium. And / or a playback device and an information processing device including the playback device.

[0002]

2. Description of the Related Art For example, as a recording medium, there is a disk cartridge using a magneto-optical disk as a rewritable recording medium. This disc cartridge can record user-desired music data on a magneto-optical disc.
Image data, processing data processed by a computer, etc. can be recorded. In addition, small information processing devices such as laptop personal computers can be installed with various application programs,
For example, music data can be reproduced, and image data and moving image data can be edited. Therefore, some small-sized information processing devices include a recording / reproducing device for a disc cartridge using a magneto-optical disc as a recording medium so that the disc cartridge can be used as an external storage device. Further, the small-sized information processing apparatus can also use a disk cartridge using a flexible magnetic disk as a recording medium as an external storage device, and a recording / reproducing apparatus for this disk cartridge is also provided. In order to improve portability, a small-sized information processing device is required to be further downsized and lightened. Therefore, a recording / reproducing device of a disk cartridge using a magneto-optical disk as a recording medium and a flexible magnetic disk are required. A recording / reproducing device of a disc cartridge as a recording medium can be selectively mounted.

[0003]

By the way, a recording / reproducing apparatus for a disk cartridge having a flexible magnetic disk as a recording medium is provided with an ejecting mechanism for ejecting the disk cartridge mounted in the mounting portion. In this eject mechanism, an eject operation button is provided in the vicinity of the insertion / ejection opening of the disc cartridge, and when the eject operation button is pressed by the user, the disc cartridge mounted in the mounting portion can be ejected by the mechanical mechanism. It is like this. A disk cartridge having a flexible magnetic disk as a recording medium has a very small storage capacity as compared with a disk cartridge having a magneto-optical disk as a recording medium. Even if the disc cartridge is ejected during the recording operation on the flexible magnetic disc due to an erroneous operation, there is little missing data, and the TOC (Table Of Contents) is not updated and the data is destroyed. Even if it happens, a small amount of information signal is lost and the damage to the user is small.

On the other hand, a disk cartridge using a magneto-optical disk as a recording medium has a much larger storage capacity than a disk cartridge using a flexible magnetic disk as a recording medium. When the recording / reproducing apparatus for the disc cartridge using the magneto-optical disc as the recording medium has the above-described mechanical eject mechanism, if the disc cartridge is ejected during the recording operation on the magneto-optical disc by an erroneous operation. , TOC is not updated after the information signal is recorded, and all data stored in the magneto-optical disk is lost. Therefore, for the user, the amount of lost data is extremely large.

Due to the above problems, it is necessary to prohibit the ejection of the disc cartridge during the recording operation in any disc cartridge. Therefore, an eject mechanism that mechanically prohibits the ejection of the disk cartridge during the recording operation can be provided in the recording and / or reproducing apparatus. That is,
With this eject mechanism, even if the eject operation button is pressed by the user during the recording operation, the disc cartridge is prevented from being ejected from the mounting portion. However, adding a mechanical mechanism that further prohibits the ejection during the recording operation to the mechanism that mechanically ejects the disc cartridge mounted in the mounting portion is
It makes the whole eject mechanism extremely complicated.
A recording and / or reproducing apparatus mounted on a small-sized information processing device has a larger vibration than a stationary information processing device, and more vibrations are applied to the recording and / or reproducing device. Therefore, if the eject mechanism becomes complicated, the recording and / or reproducing device fails. It becomes easier.

Further, as described above, the small-sized information processing apparatus has a larger vibration than the stationary information processing apparatus, and more vibrations are applied to the small-sized information processing apparatus. The device is provided with a damper mechanism that absorbs vibration. The damper mechanism is
The mounting portion to which the disc cartridge is mounted, the magnetic head, the recording / reproducing portion such as an optical pickup are set in a floating state by using an elastic body such as rubber so that vibration is not transmitted to the recording medium or the recording / reproducing portion during recording / reproducing. Recording and reproduction can be performed reliably.

The provision of the eject mechanism having the above-mentioned mechanical mechanism for prohibiting the eject during the recording operation in the recording / reproducing apparatus having such a damper mechanism further complicates the eject mechanism. . That is, the eject mechanism is usually arranged on a base holding the mounting portion or a holder for holding a disk cartridge attached to the base, while the eject operation buttons forming the eject mechanism are arranged on the base. The eject mechanism and the eject operation button are provided in a housing that is linked by a mechanical link mechanism.
Since the base and the like are in a floating state with respect to the housing by the damper mechanism, they can move with respect to the housing. Therefore, it is not possible to mechanically link the eject mechanism and the eject operation button. However, it is very difficult and the mechanism becomes more complicated. In the recording / reproducing apparatus having such a complicated eject mechanism, the eject mechanism may be damaged if vibration is frequently applied when the recording / reproducing apparatus is mounted on a small information processing apparatus.

Therefore, as a recording / reproducing apparatus for a disk cartridge which can be mounted on a small-sized information processing apparatus, it is desirable that the eject mechanism is electrically operated and the ejection of the disk cartridge is prohibited during the recording operation. In this case, the recording / reproducing apparatus does not have its own power source, and when mounted on the mounting portion, drive power is supplied from the information processing apparatus.

Since a recording / reproducing apparatus having an electric eject mechanism is adapted to be supplied with power from a small-sized information processing apparatus, the ejection of the disc cartridge is always mounted in the mounting section of the information processing apparatus. It must be performed in a state where the information processing device is activated and cannot be performed in a state where the information processing device is detached from the mounting portion. Therefore, when the recording / reproducing apparatus is removed from the mounting section of the information processing apparatus with the disc cartridge mounted, the user again mounts the recording / reproducing apparatus on the mounting section of the information processing apparatus and the information processing apparatus starts up. It is necessary to wait until this is done before ejecting the disc cartridge, which is very troublesome.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a recording medium even when it is detached from a host device by providing electric and manual operation means. An object of the present invention is to provide a recording and / or reproducing device capable of ejecting and improving operability, and an information processing device including the recording and / or reproducing device.

Further, an object of the present invention is to prohibit ejection of a mechanical recording medium in a state where it is mounted on a host device,
It is an object of the present invention to provide a recording and / or reproducing apparatus and an information processing apparatus including the recording and / or reproducing apparatus, which prevent the recording medium from being ejected during the recording operation and prevent the recorded information signal from being unreadable.

Further, an object of the present invention is to enable mechanical ejecting and electrical ejecting, to simplify the structure of ejecting means, and to make a recording and / or reproducing device which is hard to malfunction and information provided with the recording and / or reproducing device. It is to provide a processing device.

The display panel 3 also serves as a cover that closes the surface of the apparatus body 2 on which the keyboard 4 is provided, and a display unit 5 is formed of an LCD (Liquid Crystal Display) or the like on the surface side facing the keyboard 4. ..

Further, the apparatus main body 2 is provided with a mounting portion 6 on one side surface 2a thereof, on which a plurality of types of recording / reproducing devices of external storage devices can be mounted. The mounting portion 6 is provided inside the device body 2 continuously with the insertion opening 7 provided on one side surface 2 a of the device body 6. There are two types of recording / reproducing devices mounted on the mounting portion 6 in the information processing device 1, and there are a recording / reproducing device of a disk cartridge using a flexible magnetic disk as a recording medium, and a rewritable magneto-optical disk or a reproduction-only device. Optical disc (hereinafter, this 2
The types of discs are collectively referred to as an optical disc. ) Can be selectively installed in a recording / reproducing apparatus for a disk cartridge that uses (1) as a recording medium.
