Abstract
A core slider for a rigid magnetic disk drive, including a slider body having air bearing portions, and a core chip which has a magnetic gap for writing and reading information and which is integrally secured to the slider body. The slider body consists of a ferrite section which includes at least the air bearing portions and which is formed of Mn-Zn ferrite, and a non-magnetic ceramic section formed of a non-magnetic ceramic material. The core chip is accommodated in a groove formed in the slider body and bonded to the slider body by a glass material.
Claims7
A core slider for a rigid magnetic disk drive, including a slider body having air bearing portions, and a core chip which has a magnetic gap for writing and reading information and which is integrally secured to said slider body, wherein the improvement comprises:
- at least a part of said air bearing portion being formed of Mn-Zn ferrite, and the balance of said slider body being substantially a non-magnetic ceramic material;
- said slider body having a chip-accommodating groove disposed at least partially within one of said air bearing portions;
- and
- said core chip being accommodated in said chip-accommodating groove and being bonded by a glass material to said slider body, such that said core chip is insulated from said Mn-Zn ferrite to substantially prevent magnetic flux leakage.
