摘要:
A magneto-optical recording apparatus comprising an optical head shiftable in the diametrical direction of a magneto-optical disk and capable of irradiating a light beam onto the magneto-optical disk, and a magnetic head disposed to be mutually opposite to the optical head with the magneto-optical disk interposed therebetween and capable of applying a magnetic field to the magneto-optical disk while being shifted in the diametrical direction of the magneto-optical disk, wherein the magnetic head is shiftable in the diametrical direction of the magneto-optical disk together with the optical head. The magnetic head consists of an E-shaped core and a coil wound around a center core element thereof, and the E-shaped core is so formed that the sectional length of the center core element in one direction extending toward two side core elements becomes equal to or shorter than the sectional length in another direction orthogonal thereto. The magnetic head is so disposed that the orthogonal direction of its core becomes coincident with the diametrical direction of the magneto-optical disk.

The present invention is to provide a new compound having a rough skin improving effect, excellent in safety, excellent in texture in use, especially free of sticky feeling, excellent in refreshing feeling, and capable to improve the base agent stability as a component. An alkylene oxide derivative is characterized by being represented by the below-described general formula (I): (formula I) Z—{O-[(AO)a-(EO)b]-R}2 (I) (In the formula, Z is the residue obtained by removing hydroxyl groups from the dimer diol, EO is an oxyethylene group, AO is an oxyalkylene group having 3 to 4 carbon atoms, and the addition form is block-type. The symbols a and b are the average addition mole numbers of the above-described oxyalkylene group and the oxyethylene group, respectively, and they are 1≦2 a≦150 and 1≦2 b≦150. The percentage of the oxyethylene groups with respect to the sum of the oxyalkylene groups having 3 to 4 carbon atoms and the oxyethylene groups is 10 to 99 mass %. Rs may be either identical to or different from each other, and they are hydrocarbon groups having 1 to 4 carbon atoms.)

摘要:
The present invention relates to a recording medium recorded with audio data and general data (including image data for computers and character data) mixed together, provided with data for each control region, where by providing a special simple control region, editing of complicated control regions does not have to be carried out and a memory region is not necessary as a working region for editing. The present invention also provides a playback device where playback can be achieved without mixing the simple control region with the control region for the audio and general data and, by also recording copy-protection information at the simple control region, a playback operation from a recording medium which has been copied illegally will not be possible. The present invention further relates to a recording device a recording device for updating each control region while data updating is being carried out at the recording medium.
摘要:
A recording medium has a user recordable area in which two types of information may be recorded, such as audio data and user data, and a control area having a first area for management information regarding the first type of information and a second area for management information regarding the second type of information. A reproducing apparatus uses the first management information to reproduce the first type of information and to avoid reproducing the second type of information as the first type of information, and uses the second management information to reproduce the second type of information and to avoid reproducing the first type of information as the second type of information. A recording apparatus generates the first management information when the first type of information is recorded and generates the second management information when the second type of information is recorded.
