Description

CD player accelerator

technical field

The present invention relates to an acceleration device, and in particular to an acceleration device applied to a disk drive.

Background technique

Currently, the disc drives sold on the market, including various optical drives and disc burners, are designed to increase the rotational speed continuously in order to increase the speed of reading or writing. At present, the 50x or 52x speed optical drives on the market can rotate at about 10,000 rpm. However, if you want to increase the speed, there will be problems with shaft vibration and noise. Moreover, the current increase in rotation speed is a step-by-step method, and the progress is quite slow.

Contents of the invention

In view of this, the object of the present invention is to provide a disk drive acceleration device, which adopts the relative reverse rotation design of the disk and the reading mechanism to generate a multiplied relative speed, so as to accelerate the reading or writing ability and efficiency of the disk drive .

A disc drive acceleration device according to one aspect of the present invention includes a tray, a rotating mechanism and a reading mechanism. The tray is used to carry the disk. The rotating mechanism is arranged on the tray and has a first rotating part and a second rotating part. The first rotating part and the second rotating part rotate around the same rotating shaft. The first rotating part drives the disk to rotate in a first direction. The reading mechanism is driven by the second rotating part to rotate in the second direction for reading the disc. The first direction and the second direction are opposite directions.

A disc drive acceleration device according to another aspect of the present invention includes a tray, a rotating mechanism and a read-write mechanism. The tray is used to carry the disk. The rotating mechanism is arranged on the tray and has a first rotating part and a second rotating part. The first rotating part and the second rotating part rotate around the same rotating shaft. The first rotating part drives the disk to rotate in a first direction. The read-write mechanism is driven by the second rotating part to rotate in the second direction for reading or writing the disc. The first direction and the second direction are opposite directions.

In order to make the above-mentioned purposes, features and advantages of the present invention more comprehensible, a preferred embodiment is specifically cited below, and is described in detail in conjunction with the accompanying drawings as follows:

2B is a side view of the reading mechanism and the rotating mechanism of the disk drive of the present invention.

Detailed ways

The disc drive acceleration device proposed by the present invention uses the way that the disc and the reading mechanism rotate in different directions to accelerate the speed of reading or writing. The disk drive can be a CD drive or a CD burner, and the CD drive is used in the following embodiments for illustration.

Please refer to FIG. 1 , which is an exploded view of a disc drive according to a preferred embodiment of the present invention. The optical drive 200 includes an upper casing 210 and a lower casing 250 , and the accommodating space formed by the upper and lower casings 210 and 250 is used for accommodating the tray 220 , the rotating mechanism 230 and the reading mechanism 240 . The tray 220 is used to carry a disk (not shown) and preferably has a circular disk loading area 222 . The rotating mechanism 230 is disposed on the tray 220 . The reading mechanism 240 includes a carrier 242 and a reading head 246 , and the reading head 246 is disposed on the carrier 242 . The carrier 242 also has a track 244 on which the read head 246 reciprocates. In this embodiment, the track 244 is preferably rectangular, the read head 246 is preferably a reciprocating read head, and the carrier 242 preferably has an approximately rectangular structure with arc-shaped edges.

Please refer to FIGS. 2A and 2B , which are respectively a top view and a side view of the reading mechanism and the rotating mechanism of the disk drive of the present invention. The rotation mechanism 230 has a first rotation part 232 and a second rotation part 234. The first rotation part 232 and the second rotation part 234 rotate around the same rotation axis. The first rotation part 232 is used to drive the disc (not shown) to the first direction. D1 rotates. The second rotating part 234 drives the reading mechanism 240 to rotate in the second direction D2 opposite to the first direction D1, so that the reading mechanism 240 reads the disk in the loading area 222 in FIG. 1 .

In this embodiment, the tray 220 has a preferably circular chip loading area 222, and the carrier 242 of the reading mechanism 240 is preferably an approximately rectangular structure with arc-shaped edges, and the arc-shaped edges correspond to the chip loading area 222. perimeter. When the first rotating part 232 of the rotating mechanism 230 drives the disc to rotate in the first direction D1 , the second rotating part drives the reading mechanism 240 to rotate in the second direction D2 in the loading area 222 . At this time, the arc-shaped edge of the carrier 242 rotates along the periphery of the circular chip loading area 222 . At the same time, the read head 246 can reciprocate back and forth on the track 244 of the carrier 242 to read data.

However, those skilled in the art of this embodiment can understand that the technology of this embodiment is not limited thereto. For example, the first direction D1 may be a counterclockwise direction or a clockwise direction. The optical drive 200 of this embodiment can also be an optical disc burner, the only difference is that the read head 246 is used as a read/write head, which can improve the efficiency of disc read and write.

The disc drive acceleration device disclosed in the above-mentioned embodiments of the present invention has the design of rotating parts in different directions through the rotating mechanism 230, which can drive the reading mechanism 240 to rotate reversely while driving the disk to rotate, so that the reading mechanism 240 and the disk ( (not shown) doubles the relative rotational speed, thereby accelerating the reading capability and efficiency of the optical drive 200 .

In summary, although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person familiar with the art may make various modifications without departing from the spirit and scope of the present invention. Equivalent changes or replacements, so the protection scope of the present invention should be defined by the attached claims of the application.
