positioner

The hard disk's positioner moves the read/write head to the correct track.

Definition

Noun: 1. A device that moves something to a specific location or orientation: In technology and engineering, a positioner is a type of actuator designed to move an object to a precise, predetermined position. 2. (Computer Science) A specific actuator for a read/write head: In computing, a positioner is the precise mechanical component that moves the read/write head of a disk drive directly to the correct data track on a storage disk.

Usage Examples
  • Noun:
    • The robotic arm uses a high-accuracy positioner to place components on the circuit board.
    • A malfunction in the hard drive's positioner can lead to data read errors.
    • Engineers calibrated the optical positioner for the laser cutting machine.
Advanced Usage
  • "Voice coil positioner": A common type of actuator used in modern hard disk drives, known for its speed and precision in moving the read/write head.
    • The voice coil positioner allows for very fast access times on the solid-state hybrid drive.
Variants and Related Words
  • Position (verb): To place or arrange something in a particular location.
    • He positioned the microphone carefully before the interview.
  • Positioning (noun): The action of placing or arranging something.
    • The precise positioning of the satellite is critical for communication.
Synonyms
  • Actuator
  • Mover
  • Manipulator (in a technical/robotic context)
Notes on Meaning

The term "positioner" is highly technical. Its primary and most common use is within fields like computer hardware engineering, robotics, and manufacturing automation. It refers specifically to a device that provides controlled movement to achieve a set position, rather than continuous motion. In everyday language, a simpler term like "mover" or "actuator" might be used, but "positioner" emphasizes the precision and final targeted location of the movement.
