Abstract

Provided are a functional cylinder body, including a plurality of layers having magnetic patterns and non-magnetic patterns formed adjacently, and a manufacturing method therefor. The functional cylinder body comprises at least: a cylinder main body; a first functional pattern part, which includes first patterns and first functional patterns, the first patterns having first recess patterns and first non-recess patterns formed by forming recesses on a first material layer made of any one of a magnetic material and a non-magnetic material, the first functional patterns being made of any one of the magnetic material and the non-magnetic material embedded in the first recess patterns; and a second functional pattern part, which is formed in a position of the cylinder main body shallower than a position of the first recess patterns and has magnetic patterns of the magnetic material and non-magnetic patterns of the non-magnetic material formed adjacently.

Dependent claims

A functional cylinder body, comprising at least:

a cylinder main body;
a first functional pattern part comprising first patterns, and first functional patterns, the first patterns having first recess patterns and first non-recess patterns formed by forming recesses on a first material layer made of any one of a magnetic material and a non-magnetic material of the cylinder main body, the first functional patterns being made of any one of the magnetic material and the non-magnetic material embedded in the first recess patterns, magnetic patterns of the magnetic material and non-magnetic patterns of the non-magnetic material being adjacently formed by embedding the non-magnetic material in the first recess patterns when the first material layer is made of the magnetic material and by embedding the magnetic material in the first recess patterns when the first material layer is made of the non-magnetic material;
and
a second functional pattern part comprising second patterns, and second functional patterns, the second patterns being formed in a position of the cylinder main body shallower than a position of the first recess patterns and the second patterns having second recess patterns and second non-recess patterns formed by forming recesses on a second material layer made of any one of the magnetic material and the non-magnetic material of the cylinder main body, the second functional patterns being made of any one of the magnetic material and the non-magnetic material embedded in the second recess patterns, magnetic patterns of the magnetic material and non-magnetic patterns of the non-magnetic material being adjacently formed by embedding the non-magnetic material in the second recess patterns when the second material layer is made of the magnetic material and by embedding the magnetic material in the second recess patterns when the second material layer is made of the non-magnetic material.
