摘要： Concave grooves for forming a receiving layer for inkjet printing are provided at the inner peripheral and outer peripheral boundary portions of an application region on a disk substrate. The concave grooves are formed with a substantially V-shaped cross section, and with a depth d that is at least equal to the film thickness of the coating film within a central region between the concave grooves. A plurality of nozzles of a supply device is arrayed in a radial direction across the central region between the concave grooves, and a substantially constant quantity of coating liquid per unit of surface area is applied so as to form a coating film of a predetermined thickness. The applied coating liquid portions are flattened by a mutual leveling effect. During drying, the coating film inside the concave grooves does not dry first, but rather dries and contracts at substantially the same time as the coating film within the central region, meaning a receiving layer of uniform film thickness can be formed over the entire central region.

摘要： A pickup is moved in the radial direction of a partial CD-R, and the end position of a recorded area in the partial CD-R is detected based on a feature signal (on track signal) in the radial direction obtained during the movement. Information recorded in the recorded area is reproduced based on the detected end position, so that an accessing inability can be avoided, and the information in the recorded area can correctly be reproduced. Thus, information recorded in the partial CD-R can correctly be reproduced.

摘要： A magnetic head slider has a magnetic head mounting surface holding a magnetic head, to be kept closest to a magnetic disk when the magnetic head slider is in operation, a slider rail surface contiguous with a surface, on the side of an air inlet end, and opposite sides of a portion, near an air outlet end, of the magnetic head and extending near to the air outlet end, a step bearing surface formed at least on the side of the air inlet end of the slider rail surface, and a negative-pressure groove formed so as to surround the step bearing surface. The magnetic head mounting surface is typically formed on an alumina protective film protecting the magnetic head. The variation of the flying height of the magnetic head slider with respect to a rolling direction is reduced and a proximity ability to approach the magnetic disk is improved.

摘要： A recording apparatus, a recording method, and a recording medium, which allows a search operation based on a second segment information signal representing finely divided segments of a recording signal even in a player which can perform only a searching operation of a first segment information signal representing large segments of the recording signal. When a change of the second segment information signal of a signal to be recorded is detected, the first segment information signal being formed is updated and the first segment information signal is recorded together with an audio signal. That is, the second segment information signal of the signal to be recorded is converted into the first segment information signal and recorded together with the audio signal.
