    摘要: A recording apparatus for recording, on an optical disk recording medium which is computer readable, data management information for managing N (N is an integer) pieces of data as a data group, and total management information for managing M (M is an integer) pieces of the data group. Time zone information (TM_ZONE) indicating a time difference between a world standard time and a standard time in a predetermined location is recorded on the total management information. Further, on respective data management information is recorded, recording time zone information (REC_TM_ZONE) at a time of recording data indicating a time difference between the world standard time and a standard time in a location where the data have been recorded, and first and second data recording time information.

    摘要: On a single chip are formed a plurality of magnetoresistance effect elements provided with pinned layers having fixed magnetization axes in the directions that cross each other. On a substrate 10 are formed magnetic layers that will become two magnetic tunnel effect elements 11, 21 as magnetoresistance effect elements. Magnetic-field-applying magnetic layers made of NiCo are formed to sandwich the magnetic layers in plan view. A magnetic field is applied to the magnetic-field-applying magnetic layers. The magnetic field is removed after the magnetic-field-applying magnetic layers are magnetized in the direction shown by arrow A. As a result of this, by the residual magnetization of the magnetic-field-applying magnetic layers, magnetic fields in the directions shown by arrows B are applied to the magnetic layers that will become magnetic tunnel effect elements 11, 21, whereby the magnetization of the pinned layers of the magnetic layers that will become magnetic tunnel effect elements 11, 21 is pinned in the directions shown by arrows B.

    摘要: A protector protuberance is formed on a head slider incorporated in a recording medium drive such as a hard disk drive. The protector protuberance is allowed to collide against a contamination on a recording medium in front of a head element mounted on the head slider. The head element can be protected from collision against the contamination behind the protector protuberance. The protector protuberance is located as close to the head element as possible. Even with a smaller protector protuberance, the front and rear support protrusions contact the recording medium so as to hold the slider body above the surface of the recording medium. An increase can be prevented in the adsorption acting between the slider body and a lubricant agent spreading over the surface of the recording medium. A smaller protector protuberance enables the head element to approach the recording medium as close as possible upon read/write operations.

    摘要: A glass substrate for a magnetic recording medium has a textured surface having numerous grooves extending in the circumferential direction of the glass substrate. The average roughness of the textured surface is 0.4 nm or less. The number of the grooves is 15 or more per micrometer. The average depth of the grooves is 2 nm or less. The grooves are formed by mechanical texturing using a texturing liquid applied between a texturing tape and the surface of a blank glass substrate rotating. The texturing liquid is an aqueous dispersion of fine diamond abrasive grains.
