摘要： A head suspension assembly includes a head, a load beam carrying the head at one end, a resilient member joining the load beam and a carriage, and a pivot bearing provided between the load beam and the carriage and structured so that the load beam is movable in a direction perpendicular to a record medium so that the load beam rocks. The head suspension assembly is structured so that the resilient member has narrow sections for reducing the width of the resilient member to a width smaller than that of both ends of the resilient member that are symmetrical with respect to a centerline of the resilient member. The distal end of the resilient member is joined to the carriage and the resilient member has an opening (hole) in the center thereof. This structure provides a highly shock-resistant and thin head suspension assembly.

摘要： Instead of directly performing defect inspection using a master information carrier, an inspection substrate is prepared to then bring the master information carrier in close contact therewith, to thereby transfer a defect on the master information carrier to the inspection substrate, thus indirectly inspecting any defect of the master information carrier on the inspection substrate. Defect inspection is performed on the first-state inspection substrate before close contacting, so that a defect inspection result on the second-state inspection substrate after close contacting and that on the first-state inspection substrate are compared to each other.

摘要： The disclosed suspension assembly (S) for carrying a magnetic recording head in close following relation to a recording disc includes an improved arrangement for supplying a load to the recording head. The suspension assembly (S) includes a flexible gimbal section (10a) for mounting the recording head and accommodating dampened pitch, roll and transverse movements. The head load arrangement comprises a flexible cantilevered spring tongue (10b) and an elongate rigid load member (20) that extends from the free end of the spring tongue to contact the suspension assembly (S) adjacent the recording head. The load member (20) is configured to cause the spring tongue (10b) to resiliently deflect by a predetermined amount, resulting in a predetermined head load being supplied through the load member to the recording head.

摘要： A master information carrier is made to overlap with a magnetic recording medium being a magnetic recording medium in an adhering state, and a pattern corresponding to information signals on the master information carrier is transferred to the magnetic recording medium, thereby magnetically transferring a magnetized pattern of information signals to the magnetic recording medium. Thereafter, an urging force to the magnetic recording medium side is applied to the master information carrier, and in the urging force applied state, a gas under pressure is supplied on the adhering/joining surfaces of the master information carrier and the magnetic recording medium, thereby releasing the adhering state of the master information carrier and the magnetic recording medium. Then, the application of the urging force is released to continue the supply of the gas under pressure, thereby pulling away the master information carrier from the magnetic recording medium and moving them.

摘要： A master information carrier (2) with an arranged pattern formed of a ferromagnetic film in a shape corresponding to information signals is superposed on a magnetic recording medium (1) and the arranged pattern formed of a ferromagnetic film is magnetized with a magnetizing head (6), thus transfer-recording the arranged pattern into the magnetic recording medium as a magnetized pattern. The magnetizing head includes an annular magnetic circuit with a gap, and a strength of a magnetic field applied to the master information carrier by magnetic flux leaking from portions other than the gap is set to be 20% or less of that of a magnetic field applied to the master information carrier by magnetic flux leaking from the gap. Quality deterioration due to various conditions during recording can be prevented and uniform recording with less variation depending on position on the magnetic recording medium is achieved.

摘要： A master information carrier capable of manufacturing a magnetic recording medium in which a preformat recording of information signals causing no reproduction signal detection errors arising from a pulse shift of a reproduction waveform is performed. A master information carrier 1 has an array of ferromagnetic thin films 3 arranged according to the pattern of information signals and is used for forming magnetization 4 of a pattern corresponding to the array pattern of the ferromagnetic thin film 3 in a magnetic recording medium by applying a magnetic field while opposing the master information carrier 1 against a magnetic recording medium 2. Each of the ferromagnetic thin films 3 is formed such that each pattern length A becomes equal to a length including a correction amount α in addition to a length a between magnetic transition areas 6 of the magnetization 4 to be formed in the magnetic recording medium 2.
