• Integrated motor driver
device with capability to
control the spindle,
tracking,
focus and tray motors.
• This device operates on a
single 3.3V supply and
provides integrated
power FETs for all
engine motors.

Conclusions

The VLSI evolution has been and will a be major
driving force, but does not cover the whole
picture

Interfacing the real world requires for different
approaches, skills and education

Analog electronics is the bridge between the
laws of nature (physics) and computing
(software):
multidisciplinary
by
nature,
impossible to be constrained in one scheme

Lateral thinking is a key process for quantum
leaps in innovation
