1. A data storage system (1) comprises: —an optical disc (2) having a storage space (3) comprising blocks (4) of storage locations; —a disc drive (10), suitable for reading information from the disc, the drive being designed to automatically start reading a next block after having read a previous block; —a host (20), capable of cooperating with the drive; —the host being designed to send (5) commands to said drive, commanding said drive to read one or more sectors of data from said disc (2); —the host being designed to send a jump command JUMPm(X,Y;SAP) to said drive, for instructing said drive to jump to block Y after having read block X, the jump command JUMPm(X,Y;SAP) including a sequential access parameter SAP; —the drive being designed, in response to receiving a jump command JUMPm(X,Y
摘要:
A modified read-ahead (i.e., jump) command, contains a sequential access parameter SAP, JUMPm(X,Y:SAP), for instructing a disc drive to jump to block Y after having read block X. If the SAP parameter has a value indicating that a host, such as a PC, designed to recognize the SAP parameter, deliberately signals a disc drive to jump to a lower address (e.g., Y

A roll bar is provided behind seats of an open car, and there is provided a wind deflector to deflect air flow coming from the vehicle rear during the open-state driving on the roll bar. The wind deflector is configured so as to have air permeability in such a manner that an air permeability rate of its upper section is greater than that of its lower section. Part of air flow passes through the wind deflector. Since the amount of the air flow passing through the lower section of the deflector directed to the neck portion is suppressed compared to the air flow passing through the upper section, both the reducing of the air flow beyond the wind deflector and the suppressing of the passenger feeling displeasure with the air flow (against the neck portion) can be attained, and thereby the passenger can be prevented effectively from feeling displeasure.

There is provided a method for decomposing a cured epoxy resin, the method being capable of decomposing a cured epoxy resin containing silica efficiently. A cured epoxy resin containing silica is decomposed by being brought into contact with subcritical water including at least one alkaline compound selected from an alkaline metal salt and an alkaline metal hydroxide.

A roll bar is provided behind seats of an open car, and there is provided a wind deflector to deflect air flow coming from the vehicle rear during the open-state driving on the roll bar. The wind deflector is configured so as to have air permeability in such a manner that an air permeability rate of its upper section is greater than that of its lower section. Part of air flow passes through the wind deflector, and the passing speed of the air flow passing through its upper section becomes greater than that the air flow passing through its lower section. Accordingly, the air pressure decrease of the upper part of air flow becomes greater, and the whole air flow passing through the wind deflector tends to be directed upward.
