A media storage device which reads and writes data from and to a storage medium using a head prevents in advance data loss due to thermal relaxation of data recorded on the storage medium. Management information is created, in units of received write commands, for holding the recording areas on the storage medium of the write data and signal quality information; the management data is stored in a management table, and signal quality is measured, updated, and used in re-recording judgements, in write command units. Thermal relaxation state management can be performed in write command units; thermal relaxation processing is simple, and moreover degradation of recorded data due to thermal relaxation can be detected accurately, and data loss can be prevented.

The invention relates to a fuel cell stack structure capable of suppressing a drop in voltage resulting from flooding or contamination at an end in a direction in which cells are laminated, particularly in a cell at a gas outlet/inlet end. In this fuel cell stack structure, a layer which is irrelevant to power generation and in which a gas flow channel is formed is provided at least at a gas outlet/inlet end of a laminated-cell body of a fuel cell such as a solid-polyelectrolyte fuel cell. The layer is constructed of a dummy cell having a gas flow channel but no MEA. In addition, according to this fuel cell stack structure, both a fuel gas flow channel and an oxidative gas flow channel are formed in one face of the layer which is irrelevant to power generation and in which the gas flow channels are formed.

Disclosed is an optical semiconductor integrated circuit device has an opening portion in an insulating layer, which is formed in a light receiving region of a photodiode stepwise. Thus, a step of the opening portion is reduced, leading to an improvement of a step coverage of a light shadowing film formed on the insulating film so as to cover the insulating film. By the improvement of the step coverage of the opening portion, the light shadowing film located on a plane of the light shadowing film of the photodiode is not broken. A problem that a conventional light shadowing film is broken is solved in the photodiode for a blue laser beam.

In an existing optical semiconductor integrated circuit device, a multi-layered wiring layer is formed on a top surface of a substrate. Therefore, a film thickness of an insulating layer on a top surface of a photodiode could be uniformed with difficulty. Thus there was a problem in the constitution of the insulating layer wherein light incidence was caused to fluctuate, and thereby a desired sensitivity to light could not be obtained. In an optical semiconductor integrated circuit device according to the present invention, after a multi-layered wiring layer is formed on a top surface of a substrate, an insulating layer on a top surface of an anti-reflection film of a photodiode is dry-etched to remove. At this time, a barrier metal layer is used as an etching stopper film. Thereby, in the invention, a manufacturing process can be simplified and owing to adoption of the dry etching miniaturization can be realized. Furthermore, since the anti-reflection film is exposed from the insulating layer, fluctuation of incident light can be suppressed and the sensitivity to light can be improved.
