Head support device and recording regenerator having this head support device

A head support device for supporting first and second heads for at least one of reading data from and writing data to a recording medium, comprising:

• a first arm for supporting the first head, the first arm having an extending portion near the first head;
• a support member having a first contact portion for contacting the first arm and a second contact portion opposed to the first contact portion, the second contact portion having a recessed portion, the first contact portion being shifted from the second contact portion in a direction toward the extending portion;
• and
• a second arm contacted by the second contact portion for supporting the second head.

A head support device for supporting first and second heads for at least one of reading data from and writing data to a recording medium, comprising:

• a first arm for supporting the first head, the first arm having a first extending portion near the first head;
• a second arm for supporting the second head, the second arm having a second extending portion near the second head;
• and
• a support member having a first contact portion for contacting the first arm and a second contact portion opposed to the first contact portion for contacting the second arm, the second contact portion having a recessed portion, said first and second contact portions having different contact boundaries in the first and second extending directions of said first and second arms such that a natural bending frequency of the second arm is lower than a natural bending frequency of the first arm.

A head support device for supporting first and second heads for at least one of reading data from and writing data to a recording medium, comprising:

• a first arm for supporting the first head, the first arm having an extending portion near the first head;
• a second arm opposed to the first arm for supporting the second head, the second arm having a second extending portion near the second head;
• a plurality of spacers nipped between the first arm and the second arm;
• and
• a support mechanism for supporting a base end portion of the first and second arms and the plurality of spacers along a stacking direction;
• wherein the plurality of spacers include a first spacer having a first contact face contacting the base end portion of the first arm and forming a first contact portion, and a second spacer having a second contact face contacting the base end portion of the second arm and forming a second contact portion opposed to the first contact portion;
• and
• wherein the first contact portion is shifted from the second contact portion in a direction toward the first and second extending portions.

A head support device for supporting first and second heads for at least one of reading data from and writing data to a recording medium, comprising:

• a first arm for supporting the first head, the first arm having a first extending portion near the first head;
• a second arm for supporting the second head, the second arm having a second extending portion near the second head;
• and
• a plurality of spacers stacked between the first and second arms, the plurality of spacers including:
• a first spacer having a ring-shaped main body and an integrally formed extending portion extending from the main body, and further having a first surface extending over the main body and the extending portion and forming a first contact face, the first contact face having a first contact portion for contacting the first arm;
• and
• a second spacer having a ring-shaped main body and a second surface forming a second contact face, the second contact face having a second contact portion opposed to the first contact portion for contacting the second arm, the main body of the second spacer having a diameter approximately equal to a diameter of the main body of the first spacer such that the first contact portion is shifted from the second contact portion in a direction toward the first and second extending portions.

A head support device for supporting first and second heads for at least one of reading data from and writing data to a recording medium, comprising:

• a first arm for supporting the first head, the first arm having a first extending portion near the first head;
• a second arm for supporting the second head, the second arm having a second extending portion near the second head;
• and
• at least one spacer stacked between the first and second arms, the at least one spacer including a ring-shaped main body having a first surface forming a first contact face having a first contact portion for contacting the first arm and a second surface located on a side opposed to the first surface and forming a second contact face having a second contact portion for contacting the second arm, the second contact face including a recessed portion formed in at least a peripheral edge portion of the second surface such that the first contact portion is shifted from the second contact portion in a direction toward the first and second extending portions.

A disk apparatus comprising:

• a driving mechanism for supporting and rotating a disk-shaped medium;
• at least first and second heads for at least one of reading data from and writing data to the medium;
• and
• a head support device for supporting the first and second heads, the head support device comprising:
• a first arm for supporting the first head;
• a support member including a first contact portion for contacting the first arm and a second contact portion opposed to the first contact portion, the second contact portion having a recessed portion, and
• a second arm contacted by the second contact portion for supporting the second head;
• wherein the at least first and second heads are movably supported with respect to the medium.
