Ferrite magnets made of iron oxideare widely used in permanent magnets, magnetic recording media, electromagnetic wave absorbing materials, and magnetic fluids.
In anticipation of the arrival of the magnetic recording still camera era,Canon formed a task force to develop a magnetic recording color still camera in October 1981.
Diamagnetic materials cannot be used as permanent magnets or magnetic recording materials. *2 Paramagnetism and ferromagnetism Paramagnetism and ferromagnetism are the phenomena of a material inducing magnetism in the same direction as an externally applied magnetic field.
In the field of magneticmetal powder used in large capacity magnetic recording media including computer data storage tapes and video tapes for broadcast stations, we hold an overwhelming world market share of 90%.
Since Japan had apatent for the alternating-current bias method that applied to magnetic recording, researchers believed they could establish a strong engineering capability by combining the patented technology with the hysteresis motor provided they could manufacture one by themselves.
The metal detector does not affect the operation of cardiac pacemakers,mobile phones and any magnetic recording materials(tapes, cards, diskettes, etc.).
In the future, as we head towards an age of total digitalization, increasing the capacity of HDDs will be called for;and the perpendicular magnetic recording method developed by Prof. Shun-ichi Iwasaki is the innovative technology that makes this possible.
The magnetic recording still camera used the analog recording system, but the know-how and technology gained through the research and development of the SV camera laid the groundwork for today's digital cameras.
This magnetic tape is composed of a magnetic recording layer of GTC-type epsilon iron oxide and a nonmagnetic layer on a base film with a back coat covering the bottom of the tape.
Please be aware that when the magnet comes too close,it may cause malfunction to a magnetic recording mediums such as magnetic cards or precision electronic devices such as a watch.
The second was the development of hard discs for magnetic recordings, which propelled the growth of technology of motors used to rotate the disc and those used to manipulate the magnetic head.
When copying a document containing confidential information or a magnetic recording medium or any material legally owned by the operator, the user shall obtain the written consent of the operator in advance, and as for the management of copies, it is strictly according to paragraph 2.
In case of copying a document containing secret information or a magnetic recording medium etc., the member shall obtain the written consent of the Company in advance, and strictly perform the management of the reproduction in accordance with paragraph 2 will do.
In the case of duplicating a document containing confidential information or a magnetic recording medium, etc., a Member must obtain the Company's consent in writing in advance and strictly perform the management of copies in accordance with the Terms of Service.
When reproducing a document, magnetic recording medium, or other media containing Secret Information, either party shall obtain the advance written consent of the other party and handle and manage such reproductions strictly pursuant to paragraph 2.
In the case of copying a document containing confidential information or a magnetic recording medium, the User shall obtain written consent of the Company in advance, and strictly adhere to the management of the copies in accordance with paragraph 2.
When Users reproduce documents or magnetic recording media, etc., that contain Confidential Information, such Users shall obtain prior written approval from the Company or other Users and handle such reproductions under strict management in accordance with Paragraph 2.
Iron oxide particles of various sizes are important as magnetic recording materials, ferrofluids, pigments, corrosion products, and in the transport of nutrients and contaminants(heavy metals and radionuclides) in the environment.
In sum, the very possibility of magnetic recording, it was feared, would“change the whole nature of telephone conversations” and“render the telephone much less satisfactory and useful in the vast majority of cases in which it is employed.”.
The density and capacity of HDDs have been increased by improvingvarious areas such as disk smoothness, magnetic recording method, and head sensitivity. However, from the end of the 1990s, vibration of HDD spindle motor bearings became a major cause of reduced data writing/reading accuracy.
Whenever the Member reproduces or copies any document or magnetic recording medium describing or containing the Confidential Information, the Member shall obtain prior written approval of the Company, and the management of the reproductions and copies shall be strictly conducted.
Moreover, by forming the reproduction unit of the above-mentioned magnetic head as a GMR head or TMR head, adequate signal strength can be obtained even in the case of a high recording density,meaning a high-recording density magnetic recording apparatus can be obtained.
While SDK earlier announced that it will increase its HD media production capacity by 3.05 million disks per month, to 13.75 million disks per month, by March 2006, all of the new production lineswill be able to use the perpendicular magnetic recording technology.
Through his fundamental review of conventional technology and his forward leap in thinking, Prof.Iwasaki has developed a new field of magnetic recording, and has made an incomparable contribution to the creation and development of large-capacity recording technology geared to the age of total digitalization.
Magnetic materials can be used for magnetic recording systems and magnetic nanoparticles with a high magneticcoercive force are particularly important for magnetism recording media such as magnetic tapes. ε-Fe2O3, which has a large magnetic coercive force and whose particle size can be reduced 8 nm or less, receives attention as a next-generation magnetic material for magnetic data recording.
