Abstract

A magnetic head apparatus with which a magneto-optical recording and reproducing apparatus can be made thin is provided. The magnetic head apparatus includes: a supporting material having an elastic portion; a magnetic head hoisting and lowering member capable of being brought into contact with and separating from the supporting material; a magnetic head pressing member capable of being brought into contact with and separating from the supporting material of a pressing portion. The head main body is capable of moving between a first position in which the head main body approaches or is brought into contact with the information recording medium and a second position in which the head main body is far away from the information recording medium. While the head main body moves between the first position and the second position, the magnetic head hoisting and lowering member is brought into contact with the supporting material; and the pressing portion is brought into contact with the elastic portion, and the contact position of the pressing portion is closer to the side of the fixing position of the supporting material than the position in which the magnetic head hoisting and lowering member is brought into contact with the supporting material. In the second position, due to the pressing of the elastic portion, the elastic portion is elastically deformed toward the side of the information recording medium.

Dependent claims

A magnetic head apparatus, comprising:

a supporting material comprising a head main body for applying a magnetic field to an information recording medium attached to one end with a second end fixed, and an elastic portion, which is capable of being elastically deformed, between the head main body and the fixed second end;
a magnetic head hoisting and lowering member disposed between the supporting material and the information recording medium and fixed in a manner capable of being brought into contact with and separating from the supporting material;
and
a magnetic head pressing member comprising a pressing portion facing a surface opposite side to the information recording medium in both sides of the supporting material and fixed in a manner capable of being brought into contact with and separating from the supporting material,
wherein the head main body is capable of moving between a first position in which the head main body approaches or is brought into contact with the information recording medium so as to record or reproduce information and a second position in which the head main body is far away from the information recording medium as compared with the first position,
while the head main body moves from the first position to the second position, the magnetic head hoisting and lowering member approaches and is brought into contact with the supporting material;
and the pressing portion of the magnetic head pressing member approaches the supporting material and is brought into contact with the elastic portion,
a position in which the pressing portion and the elastic portion are contact with each other is closer to the side of the fixing position of the supporting material than the position in which the magnetic head hoisting and lowering member and the supporting material are brought into contact with each other;
and
in the second position, the pressing portion presses the elastic portion, so that the elastic portion is elastically deformed toward the side of the information recording medium.

A magnetic head apparatus, comprising:

a supporting material comprising a head main body for applying a magnetic field to an information recording medium attached to one end with a second end fixed, and a first elastic portion, which is capable of being elastically deformed, between the head main body and the fixed second end;
a magnetic head hoisting and lowering member disposed between the supporting material and the information recording medium and fixed in a manner capable of being brought into contact with and separating from the supporting material;
a magnetic head holding member comprising a second elastic portion capable of being elastically deformed, being substantially in parallel with the surface of the information recording medium, having one end at the side of the second elastic portion being fixed, and disposed facing the surface at the opposite side to the information recording medium;
and
a posture holding member provided in the magnetic head holding member and protruding toward the side of the information recording medium so as to face the magnetic head hoisting and lowering member,
wherein the head main body is capable of moving between a first position in which the head main body approaches or is brought into contact with the information recording medium so as to record or reproduce information and a second position in which the head main body is far away from the information recording medium as compared with the first position, and
in the first position, the posture holding portion is brought into contact with the magnetic head hosting and lowering member.
