| 20090061106 | PERPENDICULAR MAGNETIC MEMORY MEDIUM, A MANUFACTURING METHOD THEREOF, AND A MAGNETIC MEMORY STORAGE - A perpendicular magnetic memory medium capable of high-density recording and reproducing consists of a soft magnetic lining layer ( | 03-05-2009 |
| 20090155630 | Alloy nanoparticles, method of producing the same, and magnetic recording medium using alloy nanoparticles - A method of producing alloy nanoparticles includes the steps of: adding a metallic salt, a reducing agent, a stabilizing ligand, and an organic iron complex to an organic solvent selected from the group consisting of 2-20C hydrocarbon, alcohol, ether, and ester in an inert gas atmosphere to obtain a reaction liquid; and stirring the reaction liquid while heating the reaction liquid to a predetermined temperature. The grain diameter of the alloy nanoparticle is controlled by regulating the amount of the stabilizing ligand. | 06-18-2009 |
| 20090257148 | MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING AND REPRODUCING DEVICE - There is provided a magnetic recording medium which contains a substrate in the shape of a disk, and a plural of recording bit formed on the substrate, wherein a bottom face of the recording bit is disposed so as to face the substrate, a top face of the recording bit is disposed so as to correspond to the bottom face of the recording bit, and Twb is larger than Twt, where Twb indicates a width of the bottom face with respect to a radius direction of the magnetic recording medium, and Twt indicates a width of the top face with respect to the radius direction. | 10-15-2009 |
| 20090296279 | MAGNETIC RECORDING MEDIUM AND INFORMATION RECORDING DEVICE - A magnetic recording medium including: a substrate; plural information recording members that are formed of a hard magnetic material on the substrate, in each of which magnetization in a direction crossing the substrate is generated and, when the information recording members pass in a predetermined traveling direction in a magnetic field for information recording, the magnetization is directed to a direction corresponding to a direction of the magnetic field and information is recorded; and a high-permeability film that is placed on an edge on a front side of the information recording members in the traveling direction and has a magnetic permeability higher than a magnetic permeability of the information recording members. | 12-03-2009 |
| 20100097720 | MAGNETIC RECORDING/REPRODUCING APPARATUS AND METHOD OF MANUFACTURING THE SAME - According to one embodiment, a magnetic recording/reproducing apparatus includes a magnetic head and a magnetic recording medium. The magnetic recording medium includes a recording layer formed of a hard magnetic layer and a soft magnetic layer. The hard magnetic layer has a bit width corresponding to a length of a bit island in a radial direction of the magnetic recording medium. The soft magnetic layer is arranged on the hard magnetic layer. The soft magnetic layer has a width smaller than the bit width and is arranged at a position displaced in a direction away from an off-track portion of the leading edge of the magnetic head skewed at an angle. | 04-22-2010 |

| 20090271435 | DATA MANAGEMENT METHOD, DATA MANAGEMENT PROGRAM, AND DATA MANAGEMENT DEVICE - Provided is a data management method. Data corresponds to an entry including a reference to another entry and is managed in a set which is a collection of pieces of the data. The set corresponds to a linked list where the entry corresponding to the data is linked in order of addition of the data. The entry includes an insertion time sequence number inserted into the linked list and information indicating if the data has been deleted from the set. In that case, the entry is separated from the linked list at a predetermined timing. The linked list is traced to refer to the data. When the insertion time sequence number of the reference entry is later than the insertion time sequence number of the entry which has already been referred to, it is judged that the reference entry has been separated from the linked list. | 10-29-2009 |
