Disk drive apparatus with a high positional precision magnetic head

A disk drive apparatus for recording and/or playing back a signal onto and/or from a disk-shaped recording medium, said disk drive apparatus having a configuration comprising:

• a carriage transported by a linear actuator;
• a head arm attached to said carriage through a supporting-point pin in such a way that said head arm is freely rotatable;
• a magnetic head attached to said cartridge through said head arm and used for recording and/or playing back said signal onto and/or from said disk-shaped recording medium;
• and
• force applying means for naturally applying a load force to said magnetic head toward said disk-shaped recording medium.

A disk drive apparatus for recording and/or playing back a signal onto and/or from a disk-shaped recording medium, said disk drive apparatus having a configuration comprising:

• a motor for driving said disk-shaped recording medium into rotation;
• a carriage transported by a linear actuator;
• a head arm provided with an arm base made of a rigid material and a suspension implemented by a plate spring, and attached to said carriage through a supporting-point pin in such a way that said head arm is freely rotatable;
• a magnetic head attached to said cartridge through said head arm and used for recording and/or playing back said signal onto and/or from said disk-shaped recording medium;
• and
