Abstract: A recorder to write content data on a storage medium and includes: a determining section, which receives incoming content data and determines data properties thereof; a selecting section for selecting, depending on whether a predetermined condition is satisfied, either a first type of write processing to add the data to an existent file on the storage medium or a second type of write processing to write the data as a new file; and a writing section for writing the data on the storage medium by performing the selected type of write processing. The selecting section selects the first type of write processing if at least one part of the data properties of the data that have been determined by the determining section is identical with those of the data that is stored in the existent file on the storage medium but selects the second type of write processing unless this condition is satisfied.

Abstract: Continuous transfer of AV data without a break necessitates to perform replacement processing of a disk access unit and takes labor and time. A characteristic is that an HDD is disposed which writes AV data in a recording medium, that an AV recording/reproducing controller is disposed which, when there is a write error in writing of AV data in a disk access unit which is a minimum unit for continuously accessing the recording medium, controls the HDD such that this disk access unit will be skipped and said AV data will be written in the next disk access unit, that skip processing judging means is disposed, and that a replacement area is not formed in the recording medium.

Abstract: Alternation processes reduce the recording and reproducing speed of a hard disk apparatus. A hard disk apparatus comprising: an HDD 10 for recording AV data onto a hard disk; and stream controlling means 8 which is connected to the HDD 10 and thereby processes the signal of AV data transmitted from an IEEE1394 I/F 7 or the signal of AV data transmitted to the IEEE1394 I/F 7; whereby the hard disk apparatus can record and/or reproduce the AV data, wherein when AV data transfer is not normally completed for a disk access unit which is a minimum continuous unit in the access to the hard disk, an alternation process on a disk access unit basis is carried out so that another disk access unit is used hereafter in place of that disk access unit.

Abstract: A signal transmission system includes a transmitter and a receiver connected via a transmission line. When a control circuit 103 in the transmitter 200 outputs a test signal to a transmission line 123, a voltage detection section 112 in the receiver 210 determines whether a voltage value on a terminal 115 falls within a given range or not. Based on the result, the control signal generation section 113 generates an instruction as to whether or not to change the current amount of the driving current. The control circuit 103 in the transmitter 100 drives the transmission line 123 with the driving current increased or decreased based on the instruction, and again outputs a test signal. This process is repeated until the voltage on the terminal 115 of the receiver 210 comes into the range. As a result, an optimum output impedance for the control circuit 103 of the transmitter 200 can be obtained.
