Claims
- 1. A magnetic recording apparatus comprising:
- a rotational drum;
- a fixed drum;
- a magnetic head; and
- a magnetic tape;
- the rotational drum having at least one of a plurality of grooves and a head mounting portion for mounting the magnetic head on the rotational drum, whose configuration is designed by a levitation phenomenon analyzer;
- the levitation phenomenon analyzer comprising:
- a data input portion for reading data on fluid and structural components and minute structures of the magnetic recording apparatus;
- a levitation analysis portion for solving basic simultaneous equations of the fluid and the structural components on the basis of the data;
- the levitation analysis portion including a calculating portion in which a thickness of an air film among the minute structures smaller than intervals of nodal points and elements for analysis is handled as a mixed mean thickness of the air film;
- the mixed mean thickness of the air film being a sum of an arithmetic mean and a harmonic mean of a mean tape levitation height and dimensions of the minute structures; and
- a result output portion.
- 2. A magnetic recording apparatus comprising:
- a rotational drum;
- a fixed drum;
- a magnetic head; and
- a magnetic tape;
- the fixed drum having at least one of a plurality of grooves, a projection and a recess, whose configuration is designed by a levitation phenomenon analyzer;
- the levitation phenomenon analyzer comprising:
- a data input portion for reading data on fluid and structural components and minute structures of the magnetic recording apparatus;
- a levitation analysis portion for solving basic simultaneous equations of the fluid and the structural components on the basis of the data;
- the levitation analysis portion including a calculating portion in which a thickness of an air film among the minute structures smaller than intervals of nodal points and elements for analysis is handled as a mixed mean thickness of the air film;
- the mixed mean thickness of the air film being a sum of an arithmetic mean and a harmonic mean of a mean tape levitation height and dimensions of the minute structures; and
- a result output portion.
- 3. A magnetic recording apparatus comprising:
- a rotational drum;
- a fixed drum;
- a magnetic head; and
- a magnetic tape;
- the magnetic heading having a sliding face for the magnetic tape, whose configuration is designed by a levitation phenomenon analyzer;
- the levitation phenomenon analyzer comprising:
- a data input portion for reading data on fluid and structural components and minute structures of the magnetic recording apparatus;
- a levitation analysis portion for solving basic simultaneous equations of the fluid and the structural components on the basis of the data;
- the levitation analysis portion including a calculating portion in which a thickness of an air film among the minute structures smaller than intervals of nodal points and elements for analysis is handled as a mixed mean thickness of the air film;
- the mixed mean thickness of the air film being a sum of an arithmetic mean and a harmonic mean of a mean tape levitation height and dimensions of the minute structures; and
- a result output portion.
