Description

Detailed Description of the Invention

[0001]

The present invention relates to a flexible disk drive for driving a flexible disk, and more particularly to a high-density flexible disk drive for driving a large-capacity flexible disk.

[0002]

2. Description of the Related Art As is well known, a flexible disk drive is a device for recording and reproducing data on a flexible disk. In recent years, the capacity of a flexible disk has been increased, and a storage capacity of 128 Mbytes (hereinafter, referred to as a large capacity) is compared with a storage capacity of 1 M to 2 Mbytes (hereinafter, referred to as a normal capacity).
Those with are being developed. Along with this, a flexible disk drive device capable of recording and reproducing data on such a large-capacity flexible disk has been developed.

In this specification, a flexible disk drive capable of recording and reproducing data only on a large-capacity flexible disk is called a high-density dedicated flexible disk drive, and data is recorded only on a normal-capacity flexible disk. A reproducible flexible disk drive is usually referred to as a density-only flexible disk drive. Further, a flexible disk drive device capable of recording / reproducing data on / from both large capacity and normal capacity flexible disks is called a high density / normal density combined type flexible disk drive device. Further, the high-density dedicated flexible disk drive and the high-density / normal-density flexible disk drive are collectively referred to as a high-density flexible disk drive.

One of the mechanical differences between the normal-density-type flexible disk drive and the high-density-type flexible disk drive is that a carriage for holding a magnetic head is inserted into the drive. The drive means moves along a predetermined radial direction with respect to the flexible disk. In other words, while a normal-density-type flexible disk drive uses a stepping motor as a driving means, a high-density flexible disk drive uses a linear motor such as a voice coil motor (VCM) as a driving means. doing.

Next, the voice coil motor used as the driving means of the high-density type flexible disk drive will be described in some detail. Voice coil motors are disposed on both rear sides of the carriage, and are wound around a drive shaft parallel to a predetermined radial direction, and a magnetic circuit for generating a magnetic field crossing a current flowing through the boil coil. And With such a configuration, by causing a current to flow through the boil coil in a direction crossing the magnetic field generated by the magnetic circuit, a driving force is generated in the extending direction of the drive shaft based on the interaction between the current and the magnetic field. . With this driving force, the voice coil motor moves the carriage along a predetermined radial direction.

By the way, in general, a large capacity flexible disk has the same outer shape as a normal capacity flexible disk. If both of them are 3.5 inches, the horizontal, vertical and thickness dimensions are 90 mm, 94 mm and 3.
It has a flat rectangular shape of 3 mm. Therefore, it is possible to insert a large-capacity flexible disk into a normal-density dedicated flexible disk drive device.

[0007]

Even if a large-capacity flexible disk is accidentally inserted into the normal density dedicated type flexible disk drive apparatus, the circuit is write-protected, and therefore, it is inserted into the normal density dedicated type flexible disk drive apparatus. Data cannot be written to the created large capacity flexible disk.

However, since the magnetic head of the normal density dedicated type flexible disk drive device is loaded, dust adheres to the magnetic disk medium of the large capacity flexible disk. When the large-capacity flexible disk with the dust attached to the magnetic disk medium is further inserted into the high-density flexible disk drive device, the magnetic head and the magnetic disk medium may be damaged.

Therefore, the high-density flexible disk drive device can be distinguished from the normal-density dedicated flexible disk drive device so that the user can surely insert the large-capacity flexible disk into the high-density flexible disk drive device. It is desirable to do so.

Therefore, an object of the present invention is to surely insert a large-capacity flexible disk into a high-density flexible disk drive device without mistakenly inserting the large-capacity flexible disk into a normal-density dedicated flexible disk drive device. So that
It is an object of the present invention to provide a high-density flexible disk drive device which can be distinguished from a normal-density dedicated flexible disk drive device.

According to the present invention, a front bezel is provided on the front side, and this front bezel is provided with an opening for taking in and out a large capacity flexible disk and a door for opening and closing this opening. In the high-density flexible disk drive device for driving a capacity flexible disk, the front bezel visually recognizes the high-density flexible disk drive device as a normal-density dedicated flexible disk drive device for exclusively driving a normal-capacity flexible disk. It is possible to obtain a high-density flexible disk drive device characterized in that it is provided with identification means that can be distinguished.

It is possible to obtain a high-density flexible disk drive device characterized by being visually distinguishable from a normal-density dedicated flexible disk drive device.

Further, according to the present invention, the front vessel further includes an eject button for ejecting the large capacity flexible disk contained therein, and the identification means is

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will now be described in detail with reference to the drawings.

Referring to FIG. 1, a high-density flexible disk drive device according to an embodiment of the present invention includes a front vessel 20 on the front side. This front bezel 20 has an opening 21 through which a large-capacity flexible disk is inserted into and removed from the main body of the front bezel 20, a door 22 that opens and closes the opening 21, and a large-capacity flexible disk that is inserted from the main body of the front bezel 20. The eject button 30 is provided. This high-density type flexible disk drive device drives a large-capacity flexible disk housed in the main body of the front vessel 20.

The eject button 30 described above is provided on the main body of the front vessel 20 so as to project in the front-rear direction. When the eject button 30 is pressed, a large-capacity flexible disk accommodated in the high-density flexible disk drive is ejected in conjunction with an eject mechanism (not shown).

Referring to FIG. 2, the aforementioned large capacity flexible disk is designated by reference numeral 10. The illustrated large-capacity flexible disk 10 shows a state equivalent to the state inserted into the high-density type flexible disk drive of FIG.

The large-capacity flexible disk 10 includes a disk-shaped magnetic disk medium 11 and the magnetic disk medium 1.
1 and a shutter 13 slidable in the direction of arrow A. The shutter 13 has a window 13a. The shutter 13 is biased by a spring member (not shown) in the direction opposite to the arrow A direction. When the shutter 13 slides in the direction of arrow A, the window 13a of the shutter 13 is moved to the opening 12a provided in the case 12, as shown in FIG.
1, the magnetic disk medium 11 can be accessed by the magnetic head (not shown) of the high-density flexible disk drive device of FIG. 1 through the opening 12a.

The case 12 of the large-capacity flexible disk 10 substantially has a flat rectangular shape with horizontal, vertical and thickness dimensions of 90 mm, 94 mm and 3.3 mm, respectively. The aforementioned dimensions of the case 12 of the large capacity flexible disk 10 are equal to the dimensions of the normal capacity flexible disk.

Referring again to FIG. 1, in this high-density flexible disk drive device, the opening 21 is
It has a size that allows the large-capacity flexible disk 10 to be taken in and out. The size of the opening of the normal density dedicated type flexible disk drive device is also substantially the same as the size of the opening 21 of the high density type flexible disk drive device so that the normal capacity flexible disk can be taken in and out.

In this high-density flexible disk drive device, the color of the surface of the door 22 is made different from the color of the surface of the main body of the front vessel 20. This allows the user to view this high-density flexible disk drive device as a normal-density dedicated flexible disk drive device in which the surface color of the door and the surface color of the body of the front vessel are the same. Can be distinguished. When the color of the surface of the main body of the front vessel 20 is gray, for example, the color of the surface of the door 22 is different from gray, for example, green or red.

Instead, the color of the surface of the door 22 and the color of the eject button 30 are made different from the color of the surface of the main body of the front bezel 20, so that this high-density flexible disk drive device can be used as a normal-density exclusive type. You may make it visually distinguishable from a flexible disk drive device.

In this case, the color of the surface of the door 22 and the color of the eject button 30 are different from the color of the surface of the main body of the front vessel 20, and the color of the surface of the door 22 and the color of the eject button 30 are different. The same high density type flexible disk drive device may be visually distinguished from the high density type flexible disk drive device by using the same color.

Alternatively, the color of the surface of the door 22 and the color of the eject button 30 may be different from the color of the surface of the main body of the front bezel 20, and the color of the surface of the door 22 and the color of the eject button 30 may be different. By making them different from each other, the high-density flexible disk drive device may be visually distinguishable from the normal-density dedicated flexible disk drive device.

It is sufficient that at least the surface color of the door 22 and at least the surface color of the eject button 30 are different from the color of at least the surface of the main body of the front vessel 20, for example, the entire color of the door 22 and the eject button. Thirty
The overall color of the front bezel 20 may be different from the overall color of the main body of the front bezel 20.

[0028]

As is apparent from the above description, the high-density flexible disk drive device according to the present invention is
Since the front bezel is provided with an identification means capable of visually distinguishing the high-density flexible disk drive device from the normal-density dedicated flexible disk drive device, the user can correctly identify the high-capacity flexible disk as the high-density flexible disk drive device. It can be inserted into the drive device. In particular, a flexible disk drive device in which at least the surface color of the door (and at least the surface color of the eject button) is different from the color of at least the surface of the main body of the front vessel can be identified as a high-density flexible disk drive device. The user can correctly insert the large-capacity flexible disk into the high-density flexible disk drive device.
