| Areal density is the product of track and
linear or bit density on each track. Since 1997, track densities
have been increasing faster than linear densities, one principal
factor for the continuing increase in areal density. This trend
is the result of improved read/write head designs that allow
writing narrow tracks and reading information with adequate
signal amplitude. Also, the trend is the result of precise track
following based on advanced actuator mechanical designs and
improved servo technologies. The use of RVS (Rotational Vibration
Safeguard) technology also enables the use of progressively
narrower tracks. |
