Abstract
A highly-operable receiver, which shortens search operations on an HDD upon startup, a recording method thereof, and an information recorder therefor are described. The broadcast receiver includes a tuner portion for receiving a broadcast program, an MPEG decoder for converting a signal from the tuner portion to a predetermined format, and a hard disk drive (HDD) for recording the converted digital signal. Whether power was turned off normally at last use is determined when the power supply is turned on. If the power supply was turned off normally at last use, a bitmap for the HDD recorded upon the last power shut-off is input; if not, new bitmap information is created. Thus, the writing/reading operations of the HDD are better managed.
