(For example,
International PublicationNumber WO 90/04205).
In this magnetic information recording method, information of a user ID is encoded while transporting a negative film, and an electric signal is applied to a magnetic head based on the encoded information, thereby recording information on the film.

[0015]

According to the information recording / reproducing apparatus of the present invention, a recording / reproducing means for recording and reproducing magnetic information or optical information in a recording area of a photographic film to be conveyed is fixed to a guide member. It is supported so as to be rotatable about an axis parallel to the direction in which the film is conveyed, and is always urged by an urging means so as to abut on one side end of the photographic film. Therefore, even when the photographic film is meandered and conveyed during recording and reproduction of information, the guide member is pressed against one side end of the photographic film in accordance with the meandering of the photographic film, and the urging force of the urging means is applied. And can rotate around the axis while pressing one side end of the photographic film, thereby following the meandering of the photographic film. Since the recording / reproducing means is fixed to the guide member that follows the meandering of the film in this way, even if the photographic film meanders, the state of being in contact with one side end of the photographic film is always maintained, The displacement of the recording / reproducing means in the direction around the axis with respect to the recording area in the photographic film, that is, the displacement (track deviation) in the width direction of the photographic film can be eliminated.

Further , since the guide member is supported so as to be rotatable about an axis perpendicular to the image forming surface of the photographic film, the recording / reproducing means fixed to the guide member also has the same function as the image forming surface of the photographic film. It can be moved about an axis perpendicular to the axis, and can eliminate not only a track deviation but also an azimuth deviation (a deviation about an axis perpendicular to the image forming surface of the photographic film in the recording area).

In the information recording / reproducing apparatus according to the second aspect , when recording or reproducing magnetic information or optical information in a recording area of the photographic film, the photographic film is provided with a contact member provided on one side end of a guide member. The photographic film is guided in the transport direction in a rolling contact state, that is, in a state in which the friction between one side end of the photographic film and the contact member is reduced. Therefore, when guiding the photographic film in the transport direction by the guide member, friction of the guide member and the photographic film,
The generation of wear and shavings can be suppressed.

In the information recording / reproducing apparatus according to the third aspect , when magnetic information or optical information is recorded / reproduced in the recording area of the photographic film, one end of the photographic film has a small friction coefficient of the guide member. It is guided in the transport direction in a state where it is in contact with. Therefore, when the photographic film is guided in the transport direction by the guide member, it is possible to suppress the generation of wear and shavings of the guide member and the photographic film.

In the information recording / reproducing apparatus according to the fourth aspect , a pressing means is provided, and the photographic film is pressed against the recording / reproducing means by the pressing member, that is, the recording area of the photographic film and the recording / reproducing means are provided. The magnetic information or the optical information can be recorded and reproduced in the recording area of the photographic film with the contact property of the photographic film improved. In addition, if the pressing member is separate from the guide member, even if the friction between the pressing member and the photographic film is large, the guide member is independent of the pressing member at one side end along the transport direction of the photographic film. The recording / reproducing means can move following the meandering of the photographic film.

In the information recording / reproducing apparatus according to the fifth aspect , the recording / reproducing means is fixed, is rotatably supported about an axis parallel to the photographic film transport direction, and is provided with one side end of the photographic film by the urging means. A first guide member that is in contact with the section is provided. Therefore, the track deviation can be eliminated by the same operation as in the first aspect. Further, claim 6
In the information recording / reproducing apparatus, the photographic film is fixed in the vicinity of the photographic film conveyance path so as to face the first guide member, and guides the photographic film in the conveyance direction with the other side end of the photographic film in contact with the first guide member. A second guide member is provided, and the photographic film is transported while being sandwiched between the first guide member and the second guide member.
Stable transport of photographic film.

Further , since the first guide member is supported so as to be rotatable about an axis perpendicular to the image forming surface of the photographic film, not only track deviation but also azimuth deviation can be eliminated.

[0022] In the information recording and reproducing apparatus according to claim 6, the first recording and reproducing means is the one abutment with a side end portion of the conveying path is fixed in the vicinity and the photographic film of the photographic film is fixed A guide member is provided. The photographic film is disposed in the vicinity of the conveyance path of the photographic film so as to face the first guide member, and is supported so as to be rotatable about an axis parallel to the photographic film conveyance direction. A second guide member is provided which is always urged to be in contact with and guides the photographic film in the transport direction. Therefore, in recording and reproducing information, even if the photographic film is conveyed in a meandering manner, the second guide member is pressed against one side end of the photographic film in accordance with the meandering of the photographic film, and The photographic film can rotate around the axis against the urging force, and can rotate around the axis while pressing the other side end of the photographic film, so that it can follow the meandering of the photographic film. Therefore, even if the photographic film meanders, the recording / reproducing means maintains the state of being in contact with the other side end of the photographic film, and can eliminate track deviation.

Further , since the second guide member is further supported so as to be rotatable about an axis perpendicular to the image forming surface of the photographic film, not only track deviation but also azimuth deviation can be eliminated.

[0024] In the information recording and reproducing apparatus according to claim 7, the other side of the photographic film on one side edge and the abutting portion and the second guide member of said photographic film of said first guide member of the first guide member Since the portion in contact with the end is formed of a material having a small coefficient of friction, when the photographic film is guided while being sandwiched between the first guide member and the second guide member, the guide member and the photographic film may be worn out. Generation of shavings can be suppressed.
