~DESCRIBING OF THE MAIN PARTS IN APPLE IPOD CLASSIC~

One of the main parts in the Apple iPod Classic is a hard drive. The function of this main part is the main storage space inside the iPod. It is a permanent storage component unlike the RAM (system memory). It is possible for the iPod to function without a hard disk. This iPod video uses a 30-GB Toshiba 1.8-inch hard drive (model MK3008GAL), featuring 4200 rpm and a USB interface. It weighs 1.7 ounces (48 grams) and fits 30 GB onto a single platter, squeezing in 93.5 gigabits per square inch. To fit so much into so little space, the drive uses smaller and lighter sliders (which keep the right spacing between the read/write heads and the recording surface) and a more sensitive thin-film technology on the heads and the platter. The increased sensitivity allows for a greater number of recorded bits per square inch. Hard drive is cannot be used if didn't have a motherboard.

The another main parts of Apple iPod Classic is a motherboard. Its function is the central or primary circuit board making up a complex electronic system, such as a modern iPod. All of the chips and memory devices that make an iPod run are situated on the motherboard.In the image, we also can see the Click Wheel controller. A "mixed-signal array" is a chip that can deal with both analog and digital data. In the case of the Click Wheel, the controller has to accept analog data generated by the movement of a finger over the surface of the wheel and turn it into digital data the microprocessor can understand. In the above is the images of the minor parts of the Apple iPod Classic motherboard.
