Abstract

Disclosed are a magnetic tape capable of being wound regularly, and an apparatus and a method by which the tape is wound regularly. The tape-shaped recording medium, which includes a tape-shaped support body and a recording layer being formed on a surface of the support body, is curved laterally over its whole length and said tape-shaped recording medium being curved laterally over its whole length and having a surface arching across a whole width of the medium. Furthermore, it is preferable that a curved amount of the medium ranges from 0.5 mm/m to 4.0 mm/m and an arched amount of the medium ranges from 0.3 mm to 2.0 mm.

Claims (24)

1. A tape-shaped recording medium comprising:

a tape-shaped support body; and

a recording layer being formed on a surface of the support body,

said tape-shaped recording medium being curved laterally over its whole length, and having a surface arching across a whole width of the medium,

wherein a curved amount of the medium ranges from 0.5 mm/m to 4.0 mm/m, and an arched amount of the medium ranges from 0.3 mm to 2.0 mm.

2. The tape-shaped recording medium according to claim 1 ,

wherein the support body is selected from a group consisting of a polyethylene terephthalate film, a polyethylene naphtahalate film, and an aramid film.

3. The tape-shaped recording medium according to claim 1 ,

wherein the support body is selected from a group consisting of a polyethylene terephthalate film, a polyethylene naphtahalate film, and an aramid film.

4. The tape-shaped recording medium according to claim 1 ,

wherein the arched amount indicates a distance between a side edge and a top of the arched medium.

5. The tape-shaped recording medium according to claim 4 ,

wherein a back coat layer is formed on the other surface of the support body, and

wherein the arched amount is adjustable by changing a thickness of the recording layer and a thickness of the back coat layer.

6. A tape-shaped recording medium comprising:

a tape-shaped support body; and

a recording layer being formed on a surface of the support body,

said tape-shaped recording medium being curved laterally over its whole length, and having a surface arching across a whole width of the medium,

wherein a curved amount of the medium ranges from 0.5 mm/in to 4.0 mm/in, and an arched amount of the medium ranges from 0.3 mm to 2.0 mm, and

wherein the tape-shaped recording medium is wound around a hub with a winding tension ranging from 0.8 N/cm to 0.9 N/cm.

7. The tape-shaped recording medium according to claim 1 ,

wherein the tape-shaped recording medium further comprises a magnetic tape.

8. The tape-shaped recording medium according to claim 6 ,

wherein the tape-shaped recording medium further comprises a magnetic tape.
