Abstract: An optical disc includes a disc base plate (21) of a light-transmitting synthetic material having a recess to mount a magnetic plate (26), and a holding part (29a), integral with the disc base plate (21), loosely to hold the magnetic plate (26) mounted in the recess with respect to the disc base plate (21). It is possible with the present optical disc to prevent distortion of the disc base plate (21) which would otherwise be caused by the difference in thermal expansion coefficients of the two components to inhibit double refraction of the disc base plate (21) caused by such distortion so as to maintain good recording/reproducing characteristics.

Abstract: An optical recording medium is provided which has a substrate and a signal recording layer provided on the substrate and in which an information signal is recorded in the form of microscopic pits. A light beam is focused on the signal recording layer and some change of the light beam carried by a return light from the signal recording layer is detected to read the information signal recorded on the signal recording layer. The optical recording medium has a diameter of 65 mm or less and a thickness of 0.4 to 0.7 mm. An information signal recording area extends outwardly from a radial position of 12.5 mm or less from the center of the medium. The ratio in area between the information signal recording area and non-signal recording area is 3.4 or more. The storage capacity of this medium is 2 gigabytes or more. The optical recording medium has formed at the center thereof a center hole around which an annular table-abutment convexing to one side of the medium is formed. A magnetic-clamping hub is installed in the center hole and thus the medium is magnetically clamped to a rotation driving mechanism of an optical recording and/or reproducing apparatus. The compactness and high density of recording of the optical recording medium will contribute greatly to a further compact structure of a recording and/or reproducing apparatus in which the medium is to be used.

Abstract: AN ERROR CORRECTION ENCODING APPARATUS (30), FOR USE FOR EXAMPLE IN AN OPTICAL DISC RECORDING AND/OR REPRODUCING APPARATUS, COMPRISES A FIRST DELAY CIRCUIT (32) THAT APPLIES DIFFERENT AMOUNTS OF DELAY TO RESPECTIVE DATA WORDS CONSTITUTING A DATA BLOCK TO CONVERT INPUT DATA IN A FIRST ARRAY STATE INTO A SECOND ARRAY STATE. A FIRST ERROR CORRECTION ENCODER (33) GENERATES FIRST CHECK WORDS FROM THE DATA IN THE SECOND ARRAY STATE. A SECOND DELAY CIRCUIT (34) APPLIES DIFFERENT AMOUNTS OF DELAY TO THE DATA IN THE SECOND ARRAY STATE AND TO THE FIRST CHECK WORDS TO PROVIDE DATA ABD CHECK WORDS IN A THIRD ARRAY STATE. A SECOND ERROR CORRECTION ENCODER (35) GENERATES SECOND CHECK WORDS FROM THE DATA AND CHECK WORDS IN THE THIRD ARRAY STATE. THE AMOUNTS OF DELAY APPLIED BY THE FIRST AND SECOND DELAY CIRCUITS (32, 34) ARE SUCH THAT THE ARRAY STATE OF THE DATA IN THE ARRAY STATE IS THE SAME AS THE ARRAY STATE OF THE DATA IN THE FIRST ARRAY STATE.

Abstract: A magnetic head device comprising a head section 55 for applying a magnetic field to a disk. The head section 55 includes a magnetic field generating section 61 and a slider 62. The slider 62 supports the magnetic field generating section 61 and may be set in sliding contact with the disk. The magnetic field generating section 61 has a magnetic core 63 and a coil 64 wound around the magnetic core 63. The section 61 is designed to generate the magnetic field and embedded in and formed integral with the slider 62. The head section 55 excels in heat-radiating property.
