摘要： An information recording medium provides a first signal recording area (A) on which a first data is recorded, and a second signal recording area (B) which is a signal recording area outer from the first area in the radius direction, records a second data at a density higher than that of the first data, and wherein the second data includes the same contents of information as the first data. The recording density of the second data may be 2 to 10 times that of the first data. The sampling rate, the number of quantized bits, and the number of pixels of the second data may be more than the sampling rate, the number of quantized bits, and the number of pixels of the first data, respectively. The first data may be recorded at a fixed transfer rate, and the second data may be recorded at a variable transfer rate. A music signal of an audible band may be recorded for the first data, and a music signal up to an ultrasound band other than an audible band may be recorded for the second data.

摘要： A recording medium includes a substrate having a microscopic pattern, which includes a shape of continuous substance of approximately parallel grooves formed with a convex shaped section and a concave shaped section alternating on a surface of the substrate. A recording layer is formed on the microscopic pattern and a light transmitting layer has a thickness of 0.05 mm to 0.12 mm formed on the recording layer. The microscopic pattern satisfies a relation of P≦λ/NA, wherein P is a pitch of the convex shaped section, λ is a wavelength of a reproducing light beam and NA is a numerical aperture of an objective lens. The microscopic pattern also includes modulated address information formed on both side walls of the convex shaped section viewed from the light transmitting layer as a wobble, both the side walls being parallel to each other, and furthermore wherein the address information is modulated by the phase-shift keying modulation system. A reproducing apparatus is particularly suited for the recording medium.

摘要： A recording medium of electrostatic capacitance type is recorded with an information signal thereon as variation of geometrical shape of the recording surface part of the recording medium. The signal is reproduced from the recording medium by the variation, in response to the variation of geometrical shape, of the electrostatic capacitance between an electrode of a reproducing stylus tracing relatively the recording surface of the medium and the surface part. At least the surface part of the recording medium having the geometric shape variation is formed by a synthetic resin into which an electroconductive material has been admixed. The synthetic resin forms an outer surface cover of the surface part of the medium thereby to prevent exposure of the electroconductive material to the outside.
