OPTIMIZE POWER, RTV, AND COUPLED PES DURING SEEK OPERATIONS - A simplified explanation of the abstract

This abstract first appeared for US patent application 17945187 titled 'OPTIMIZE POWER, RTV, AND COUPLED PES DURING SEEK OPERATIONS

Simplified Explanation

The patent application describes a data storage device with a voice coil motor (VCM) that can operate in different modes and settings to seek towards a target track on a disk.

  • The data storage device comprises one or more disks and an actuator arm assembly with a VCM.
  • The VCM can operate in a first mode and a second mode, each corresponding to different settings.
  • The control circuitry controls the VCM to seek towards a target track using the first setting for a first duration in the first mode.
  • The VCM transitions from the first setting to the second setting in the first mode before seeking towards the target track for a second duration.
  • The VCM then transitions from the first mode to the second mode, seeking towards the target track for a third duration.

Potential Applications

This technology could be applied in:

  • Hard disk drives
  • Data centers
  • Cloud storage systems

Problems Solved

This technology helps in:

  • Improving data storage efficiency
  • Enhancing data retrieval speed
  • Optimizing disk access operations

Benefits

Original Abstract Submitted

Various illustrative aspects are directed to a data storage device comprising one or more disks, an actuator arm assembly comprising a voice coil motor (VCM), the VCM configured to operate in a first mode and a second, different mode, wherein the first mode corresponds to at least a first and a second setting, and a control circuitry configured to cause the VCM to seek towards a target track in the first mode using the first setting for a first duration, control transition of the VCM from the first to the second setting in the first mode, cause the VCM to seek towards the target track using the second setting for a second duration, and control transition of the VCM from the first to a second mode, wherein controlling the transitioning comprises seeking the VCM toward the target track in the second mode for a third duration.
