摘要

The suspension assembly for hard disk drive (HDD) is the "bridge" that allow reading, writing, and erasing electronic file data from rigid magnetic-disk media. The evolution of the suspension assembly has seen many changes driven by constant improvements in drive designs due to areal density constant grow. A 60% areal density grow per year has brought the 3.5" disk from 1-GB/platter to more than 10-GB/platter in an unbelievable short length of time. In 1999, the desktop drive makers progressed rapidly from 4.1GB/platter to 10.2- GB/platter technologies. The major mobile drive makers began shipping 3.33-GB/platter mobile designs in February and March 1999, and achieved volume shipment of 6-GB/platter mobile technology during August and September 1999. The metrology in the data storage or hard-disk-drive industry has made a fundamental transition from a laboratory-based instrument to an in-line production control tool. To be capable to follow the tremendous technology increase above mentioned. This trend is being driven by the multidimensional changes taking place in the drive industry, including: The technology transition to more sensitive MR and GMR heads, decreased fly heights, smaller form factors, and the transition from slider level processing to bar level processing. In addition, economic consideration such as decreasing product life cycle, increasing drive competitiveness, and decreasing margins are demanding increased metrology testing with real time feedback to manufacturing operations. Even thought, several years ago 2-3% sampling was sufficient to monitor manufacturing processes, the trend today is to use up to 100% in-line metrology testing. Slider certification prior to head gimbal assembly (HGA), as well as in depth test on Slider Static Attitude, (PSA, RSA) and Head Alignment (HA), are just few of the most critical measurement required for the new advanced HDD components manufacturers.
