Computer Drives - How Many Different Kinds are There?

By: Jesse Miller

Computer drives are much better at reading CD-R than stand alone DVD players. DVD players are more likely to produce glitches in the picture, but on a computer these errors are corrected. There are different removable carriers in which serially and parallel connected computer drives are enclosed. These can not be inserted in the same drive bay of the chassis unless alterations are first made to the chassis or to the portable computer drives. An important detail is to provide the universal receiving frame with the capability of interchangeably receiving different removable carriers within which serial or parallel connected computer drives are interfaced, a serial-to-parallel bridge is mounted on the printed circuit board. The computer drives are also known as disc drives.

Computer

Unlike CD-R, CD-RW computer drives can rewrite a CD-RW disc. CD-R and CD-RW drives are primarily only available for computers, so you will have to do all your recording on your computer. In addition to hardware limitations, encoding a video stream to MPEG-2 requires an extremely powerful and expensive computer and the algorithms do not work in real-time. They have been affixed to carriers that are removably received within a storage enclosure or chassis that is located remotely from a host computer. The removable carrier with its portable computer drive is simply pulled out of the chassis on an as-needed basis. In some cases, the portable computer drive that is enclosed by the removable carrier is connected for serial operation. In other cases, the computer drive is connected for parallel operation.

Such alterations would typically increase the cost and complexity of the computer system and the remote storage. The ability of a single receiving frame to automatically accommodate different removable carriers and both serially and parallel connected computer drives maximizes the flexibility of the computer system and avoids the necessity of having to make alterations to the chassis or the portable computer drives. Another one is a chassis or storage enclosure that is automatically adapted to different computer drive carriers without the inclusion of the mentioned universal receiving frame. In this case, the chassis in the receiving frame are separated from a host computer. The portable computer drives that are enclosed by respective removable carriers and connected there for either serial or parallel operation with other computer drives in the chassis are disc drives.

Connectors

It is to be understood that the backplane connector may have any suitable number of pins and size so as to be adapted to be mated to the oppositely aligned backplane connectors of the removable carriers having both serial and parallel connected computer drives enclosed. An opening is formed through the bottom of extension to permit access to a DC power connector that is connected to circuit board to provide power to the computer drive. By mounting both the interface and the serial-to-parallel bridge integrated circuit chip on printed circuit board at the back of the universal receiving frame. The remote computer drive and its chassis are interfaced with one another at the rear of receiving frame. Moreover, a single universal receiving frame can automatically accommodate different removable carriers, regardless of whether the remote computer drives are connected for serial or parallel operation.

Drives

The choice will be determined by convenience, whether you have space on your desk for a stand-alone and by how much menu authoring you want to be able to do. These computer drives are much less expensive. It is also a good idea to make sure the firmware on your computer drives are updated to the latest version.

NOTE: Desktop/Notebook computer drives are physically smaller and hold less data than full-size hard drives found in desktop computers.
