HDD carriages


Demands for HDD have been increasing mainly in the PC market, and HDD is now becoming widespread as the devices are employed for new applications, such as HDD recorders and music players, in the digital household appliance market.
The constant demand for the larger capacity has led to increase in the surface recording density of HDD year after year. The recording method has shifted from longitudinal magnetic recording to perpendicular magnetic recording and several techniques such as "discreet track media," "patterned media" and "heat-assisted magnetic recording" have been proposed, which have served to technological innovations related to HDD.
We manufacture and sell the carriages to support and drive the read/write head comprising HDD. Also we develop technology for securing high levels of clean environment and precise resonance control for mechanical vibration of a carriage required with increase in recording density while improving our production technology to efficiently supply products with high performance and reliability.
