Transcript: Sector Computer Drives What Is an Optical Drive? Block In HDDs, the actuator moves the hard drive head arm. Also known as PUH. Made of discrete passive and active components which areassembled with stringent demand of precision. Read/Write Heads Circular disk on which magnetic data is stored. HDDs usually contain multiple platters which are mountwd on the same spindle. A platter can store information on both sides, requiring two heads per platter. By Aaron Gabriel Disk Controller Physical spot on a formatted disk that holds information. Landing Zone A group of sectors that the operating system can address (point to). Can be 1,2,4,8,or 16 sectors. The bigger the block, the more sectorsit will hold. Identified by their storage methods and data encoding. Boot Sector Whats's a Platter? What Does an HDD Look Like? Also knowsn as the track. Cylinder-head-sector, also known as CHS, was an early method for giving addresses to each physical block of data on a hard disk drive. Pickup Head Spindle Cylinder What's a Hard Drive? Parts of an HDD: It's a data storage device used for storing and recieving digital information in a random-access manner. Simplified - What you store computer software on. Comprises the same track number on each platter, spanning all such tracks across each platter surface that is able to store data Spindle A subdivision of a track on a magnetic disk or optical disc. Each sector stores a fixed amount of user data. An actuator is a type of motor for moving or controlling a mechanism or system. The inner space of the hard disk where the read/write rests following a park command. It is the non-data area on the disk’s inner cylinder. Actuator The spindle is the motor in which the attached optical deivce rotates around. As simple as that! Platter Spindle Heads (read/write) Actuator Sector Block Boot Sector Cylinder Disk Controller Landing Zone A region of a hard disk, floppy disk, optical disc, or other data storage device that contains machine code to be loaded into random-access memory (RAM) by a computer system's built-in firmware. Small parts of a disk drive that move above the disk platter and transform the platter's magnetic field into electrical current or vice versa. Simplified - Small parts of a disk drive that move above the disk platter and transform the platter's magnetic field into electrical current or vice versa. The circuit which enables the CPU to communicate with a hard disk, floppy disk or other kind of disk drive. A disk drive that uses laser light or electromagnetic waves within or near the visible light spectrum as part of the process of reading or writing data to or from optical discs. Examples: CDs, DVDs, and Blu-Rays. The shaft that rotates in the middle of a disk drive. In a removable disk, the spindle remains attached to the drive, as with a CD-ROM ; with a fixed disk the spindle remains attached to the platter. Simplified - Rotating device that keeps the device spinning.
