  • Page 25 SAMSUNG HARD DISK DRIVE Abbreviation of pivot bearing, Mediator of Arm and Base which is located in the center of ARM BEARING and it can rotate smoothly. Bezel A plastic panel that extends the face of a drive so that it covers a computer's drive bay opening.
  • Page 26 SAMSUNG HARD DISK DRIVE Data is recorded on lots of circle in media in HDD, we call these circles track.. We record data at both sides of media and HDD has many media layers. so it has several tracks which have Cylinder/Trac the same radius, we call this concentric circle collection of track Cylinder.
  • Page 27 Height more specified mechanical design. Form factor Industrial specification decided diameter of Disk. 3.5", 2.5" in case of Samsung. Recording the particular signal to divide track and sector and this information should be recorded Format on disk in first before user want to store data. Be careful because formatting erase all recorded information.
  • Page 28 SAMSUNG HARD DISK DRIVE Hard Disk Drive, memory device by transferring data to permanent magnetic field rather than digital pulse. It organized HDA and PCBA. Head Read/write data on disk directly. (MIG, Thin film, MR,GMR) The damages of read/write and media cause a sudden contact between head and disk surface, Head Crash they are also occurred because of dust,particles or other contamination within HDA.
  • Page 29 SAMSUNG HARD DISK DRIVE LBA mode Logical block allocation. DOS mode to resolve 528MB capacity restriction. Light Emitting Diode. Used for signal light to all kind of electric containing computer. Low profile One of standard height of HDD, the real height is 1 inch.
  • Page 30 SAMSUNG HARD DISK DRIVE Time to perform the real order for controller, host adaptor and drive. The faster overhead is, Overhead the faster performing time. Overwrite Recorded data erased by overlapping the existing data. Parking = Landing Zone Zone When we use one HDD for multi ones dividing section logically, every memory section is Partition partition, For example, 2.5GB HDD can be used for one 2.1GB computer and one 400MB.
  • Page 31 SAMSUNG HARD DISK DRIVE RETAINER Component could fix bearing when inserted to ARM. RING Encoding method "run length limited data" to magnetic pulse. It can store data 50% more than MFM(Modified Frequency Modulation) method. Return Material Authorization Searching only memory. memory would not erase during off, so we use this to program or data need not change in PC.
  • Page 32 IBM, establish fixed magnetic disk within airtight space then head rise on connecting Disk disk, we apply to all kind of hard disk drive now days. Window Make hole so head for servo write to write locational information could enter inside of HDD.
