Abstract: The present invention provides a measure for getting read/write control information stored within a space of a predetermined size in a format that ensures compatibility with media of a lower order or an older generation even if the size of the read/write control information increases significantly as the storage densities of information storage media rise in the near future. On an information storage medium, a data sequence is writable as a combination of marks and spaces. The medium has at least one information storage layer, which has an information storage area to store information and a control information area for use to perform a read/write operation on the at least one information storage layer. The control information area stores at least one set of control information, which includes a first kind of write pulse information including information to be used as a reference value and a second kind of write pulse information including information to be used as an offset value.

Abstract: An information storage medium according to the present invention has n information storage layers (where n is an integer and n?3), on which data can be written with a laser beam and which are stacked one upon the other. Each of the n storage layers has a test write zone for determining the recording power of the laser beam. When those n layers are counted from the one that is located most distant from the surface of the medium on which the laser beam is incident, there is a bigger radial location difference between the outer peripheral end of the inner one of the test write zones of ith and (i+1)th information storage layers (where i is an integer that satisfies 2?i?n?1) and the inner peripheral end of the other outer test write zone than between the outer peripheral end of the inner one of the test write zones of jth and (j+1)th information storage layers (where j is an integer that satisfies 1?j?i?1) and the inner peripheral end of the other outer test write zone.

Abstract: A tube-line pressure sensor of a medical-appliance driving apparatus detects the interior pressure of a tube line. If the pressure detected by a tube-line pressure sensor is equal to or less than a predetermined value, a first solenoid valve is closed, while a second solenoid valve is opened, whereby a gas is supplied from a secondary gas tank to the tube line. The amount of gas supplied to the tube line is calculated based on a pressure change in the tank detected by a tank pressure sensor. In actual use, natural gas leakage during normal operation can be clearly distinguished from abnormal gas leakage due to an accident. The interior pressure of the tube line is detected at a time when the balloon is about to inflate from the deflated state, and a gas supply system supplies the driving gas to the tube line so that the detected pressure becomes a preset pressure value. A controller can change the preset pressure value.
