Disk drive manufacturers are in a relentless race to deliver the highest data storage capacity at the lowest cost. To increase storage capacity without adding disks (which would result in a larger and more costly drive), disk drive makers increase the density of the data stored on the disk. Two methods of increasing data density, or areal density as it is called, are:
1. Increase the number of data tracks per disk
2. Increase the number of data bits recorded per linear inch on each data track
As disk drive makers pack more bits of data onto each disk, new suspension assembly designs and features are needed to solve problems associated with increased areal density. Our suspension assembly solutions address:
Lower flying heights - Suspension assemblies must more precisely position the head to fly closer to the disk to read smaller and weaker signals.
Smaller recording heads – Miniaturized suspension assembly designs are needed to hold tiny recording heads that are the size of a pepper flake.
Expanded functionality – New suspension assembly designs must accommodate “onboard” components and sensors for improved data transmission.
Higher areal density translates into lower cost/gigabyte of storage. The combination of increasing storage capacity and falling cost/gigabyte continues to fuel the demand for disk drive storage.
