Abstract:
A patterned magnetic recording medium including a plurality of magnetic recording domains arranged at predetermined regular intervals on a substrate, wherein the magnetic recording domains are multi-layered and comprise a soft magnetic layer interposed between a first ferromagnetic layer and a second ferromagnetic layer. The soft magnetic layer suppresses magnetic interaction between a respective one of the magnetic recording domains and neighboring ones of the magnetic recording domains.
Abstract:
A nano-imprint mold and a method of manufacturing the same are provided, which can be used for replicating a nano-scaled structure to a polymer layer. The nano-imprint mold comprises: a substrate; a pattern portion having a prominence and depression pattern formed on the substrate; a hard layer formed of a material with a hardness higher than the pattern portion on a surface of the pattern portion; and a separation layer formed on a surface of the hard layer. In the nano-imprint mold of the present invention, an original pattern can be uniformly replicated even on a substrate with an irregular surface. Further, the pattern can be prevented from being damaged by pressure and being contaminated by synthetic resin, resulting in better accuracy and durability of the pattern.
Abstract:
Humanized antibodies specifically binding to hTNF-α are prepared from a mouse monoclonal antibody by the CDR (complementarity determining region) grafting method, and they show an antigen binding affinity similar to the original mouse monoclonal antibody and significantly low immunogenicity. Therefore, the humanized antibodies can be effectively used for treating a hTNF-α-related disease such as rheumatoid arthritis, Crohn's disease, psoriatic arthritis, psoriasis, septicemia, asthma, Wegener's granulomatosis, inflammation, and ankylosing spondylitis.
Abstract:
A magnetic recording medium including a magnetic recording layer and a substrate that supports the magnetic recording layer is provided. At least two underlayers including a nonmetallic underlayer are placed between the magnetic recording layer and the substrate. The perpendicular magnetic recording medium uses a double-layered or tri-layered underlayer. Accordingly, a perpendicular magnetic recording layer can have a high perpendicular magnetic anisotropic energy constant Ku due to a third underlayer and have small crystal grains and a small exchange coupling due to a second underlayer below the third underlayer. Thus, the perpendicular magnetic recording layer can have a good thermal stability, high-density recording characteristics, and excellent SNR characteristics.
Abstract:
A recording medium including a perpendicular magnetic recording layer and a laminated SUL formed on a substrate is provided. The SUL includes an antiferromagnetic layer interposed between laminated structures including a magnetic layer, a non-magnetic layer and a magnetic layer. The layers may each have a thickness of 20 nm or less and the layers below the antiferromagnetic layer may be thinner than the layers on the antiferromagnetic layer. The laminated structures formed on and below the antiferromagnetic layer have unidirectional magnetic anisotropies set in the opposite radial direction to each other by an exchange bias. As a result, media magnetic domain noise can be diminished.
Abstract:
A rate 7/8 MTR code encoding/decoding method and apparatus. The encoding method includes: generating a rate-7/8 MTR code for inputting 7-bit data and outputting a predetermined 8-bit codeword; checking whether codewords satisfy a predetermined constraint condition by connecting the 8-bit codeword and a subsequent 8-bit codeword; and if the codewords do not violate the constraint condition, not converting the codewords. The decoding method includes: checking whether the codewords satisfy a predetermined MTR constraint condition by connecting a current 8-bit codeword c(k) and a subsequent 8-bit codeword c(k+1); if the codewords violate the constraint condition, converting the codewords, and if the codewords do not violate the constraint condition, not converting the codewords; and decoding each converted 8-bit codeword into 7-bit data using a predetermined MTR code. Data is reliably reproduced with high write density, and large amounts of data are stored in and reproduced from a magnetic recording information storage medium.
Abstract:
The brake dust cover structure of a vehicle prevents nearby components from being thermally damaged by insulating the brake disk from heat radiation and prevents impurities, such as pieces of stone, soil or the like, from entering into the brake disk along with air, thus preventing damage to the brake disk. The present invention further improves the cooling efficiency of the brake disk by maximizing the amount of airflow into the brake disk.

Abstract:
A head assembly for use in a VCR includes a head base, a head chip comprised of a first non-magnetic substrate block, a magneto-resistive head, a thin film head, and a second non-magnetic substrate block, an FPCB attached to the magneto-resistive head, and an FPCB attached to the thin film head. Such a head assembly can record or reproduce high density magnetic signals by virtue of the very small magnetic gaps incorporated therein. Such a head assembly can be manufactured by forming the magneto-resistive and thin film heads on a substrate wafer using layering processes. In the alternative, the magneto-resistive head and the thin film head can be formed on separate substrate wafers by using layering processes, and then combined to produce a head chip.
