A mail transmitting server includes a notification method table, a data receiver, and a notification method selector. The notification method table stores types of computer viruses and notification methods for the result of detection of computer viruses in association with each other. The data receiver receives data from a cellular phone. The notification method selector selects a method of notifying the cellular phone of the virus detection result, based on a type of a computer virus included in the data received by the data receiver.

In a portable telephone having a television receiving function that can be opened and closed in a longitudinal direction and in a transverse direction, a television broadcast can be seen in a horizontally long screen, however, a representation of an operating portion such as a ten-key remains to be a representation of the portable telephone. A key sheet (13) of the operating portion is stuck to a frame (6) sliding in a first casing (1). A cam (12) is provided in association with a first rotational axis (9). When a second casing (2) is opened in the longitudinal direction, the rotation of the first rotational axis (9) together with the second casing (2) is used to shift the frame (6) by the movement of the cam (12). The representation of the operating portion such as the ten-key is changed from the arrangement of figures for selecting a channel to the arrangement of figures for a telephone and the direction of the representation is also changed to that of a representation rotated by 90 degrees.

It is an object of the present invention to provide a method of recording information to an optical recording medium that is suited to achieving high data transfer rates.The method of recording information according to the present invention is adapted for recording information to an optical recording medium by forming on the optical recording medium a plurality of recording marks selected from a group consisting of several types of recording marks each with different lengths, wherein a bottom power of a laser beam used for forming at least one recording mark contained in the group is set to be higher than a reproducing power of a laser beam used for reproducing information. According to the present invention, since the bottom power helps to erase a recording mark, it is possible to maintain a high erase efficiency even when information is recorded by setting a high data transfer rate.

It is an object of the present invention to provide a method for recording data in an optical recording medium which can record data in a write-once type optical recording medium at a high linear recording velocity using a laser beam having a low recording power. The method for recording data in an optical recording medium according to the present invention is constituted so that when data are to be recorded in an optical recording medium including a substrate, a first recording layer and a second recording layer by projecting a laser beam whose power is modulated in accordance with a pulse train pattern including pulses whose levels are set to levels corresponding to a recording power Pw and a bottom power Pb onto the optical recording medium and forming a recording mark at a predetermined region of the first recording layer and the second recording layer, as a linear recording velocity increases, the power of the laser beam is modulated using a pulse train pattern including a smaller number of pulses whose level is set to a level to the recording power Pw, thereby forming a recording mark. According to the present invention, since the power of a laser beam is modulated using a pulse train pattern including a smaller number of pulses whose level is set to a level to the recording power Pw as a linear recording velocity increases, it is possible to record data in an optical recording medium using a laser beam having a low recording power even when a linear recording velocity is high and on the other hand, it is possible to prevent cross-talk of data from increasing even when a linear recording velocity is low. Therefore, it is possible to employ a semiconductor laser having a relatively low output even when data are recorded at a high linear recording velocity.

摘要:
An information recording method enables the precise formation of a recording mark on a recording layer having a high light transmittance such as an L1 layer of a double-layered optical recording medium. The information recording method uses the following recording strategy. A laser beam is pulse-modulated so as to create a pulse series including a write pulse of a recording power and a cooling pulse of a base power. Data to be recorded is modulated to have a length of a recording mark along a track of the recording layer. At the same time, the length of the recording mark is made to correspond to an integral multiple nT of T where T is one clock cycle. An nT recording mark corresponding to nT is recorded by using the same number of write pulses and cooling pulses when n is 4 or larger. Moreover, an average width AveTc for a single cooling pulse width Tc is set to satisfy: 1.0
