Head assembly employing microactuator in recording medium drive

A head assembly comprising:

• a plurality of heads;
• a plurality of driven members respectively supporting the head;
• a common support member designed to support the driven members for a relative movement;
• data signal lines attached to the support member for carrying a data signal of the head;
• a microactuator interposed between the individual driven member and the support member so as to cause the relative movement between the individual driven member and the support member based on a driving voltage;
• a driving signal line attached to the support member for carrying the driving voltage to the microactuator;
• and
• a resistor inserted in the driving signal line between the microactuator and a voltage source of the driving voltage.

A head assembly comprising:

• a piezoelectric element deforming in response to supply of a driving voltage;
• first and second electrodes holding the piezoelectric element therebetween and leading the driving voltage to the piezoelectric element;
• a conductive adhesive layer interposed between the piezoelectric element and at least one of the first and second electrodes;
• a driven member fixed to the first electrode so as to support a head;
• a support member fixed to the second electrode;
• and
• a driving signal line connected to the first and second electrodes so as to lead the driving voltage to the first and second electrodes.

A recording medium drive comprising:

• an enclosure defining an inner space;
• a recording medium disposed within the inner space;
• a head disposed within the inner space with respect to the recording medium;
• a driven member supporting the head;
• a support member designed to support the driven member for a relative movement;
• a microactuator interposed between the driven member and the support member so as to cause the relative movement between the driven member and the support member based on a driving voltage;
• an amplifier amplifying a voltage from a voltage source so as to generate the driving voltage;
• and
• a DC/DC converter disposed outside the inner space and designed to supply a source voltage to the amplifier.
