ABSTRACT:
Alternation processes reduce the recording and reproducing speed of a hard disk apparatus.A hard disk apparatus comprising: an HDD10for recording AV data onto a hard disk; and stream controlling means8which is connected to the HDD10and 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.
