Hard Drive

by danpiers In reply to Hard Drive

1. Stepper motor - Motor with discrete rotor positions (usually a few degrees each within one 360-degree revolution.) Used to control the location of the R/W head in relation to the spinning disk. Not used in most newer hard drives. Replaced by Voice Coil actuators. Still used in most floppy drives.
2. WORM Drive - Acronym for Write-Once/Read-Many. Refers to CD/R (and DVD) types of media that you create one time and then are able to reaad anytime after that. Once you finish writing to the CD/R, it cannot be erased or written to again.
3. R/W Head - R/W stands for Read/Write. Magnetic sensors placed inside a hard drive that can effect and sense changes in the magnetic media on the spinning disk. They are usually placed at the end of a long arm, and positioned over a discrete track on the disk. The arm moves the head from track to track and is controlled by a voice coil actuator.
4. Motor - This is probably a reference to the motor that spins the disk at either 3600rpm, 5400rpm or 7200rpm.
5. Carriage - A very generic term referring to the framework or chassis that all parts are mounted on.
6. Track zero sensor - A mechanism, in place, to correct the head positioning should it lose its calibration during operation.
7. Berg Connector - Attachment of contacts to printed circuit boards using "ball-grid-array" solder technology called MEG-Arrays. Berg is the company that introduced the technology.

Hope this was helpful.
