Abstract:
An apparatus for recording a signal onto a hard disk apparatus and reproducing the signal recorded onto the hard disk apparatus, comprising:signal inputting means for inputting the signal; time compression means for compressing the input signal along a time axis per a time T1 to obtain a unit of time compressed writing signal; writing means for writing the unit of time compressed writing signal onto the hard disk apparatus via a magnetic head; reading means for reading an arbitrary unit of time compressed writing signal which was previously written onto the hard disk apparatus, from the hard disk apparatus via the magnetic head to obtain a unit of time compressed reading signal; time decompression means for decompressing the unit of time compressed reading signal along the time axis so as to obtain a decompressed signal for reproduction; and control means for controlling the writing means and the reading means such that a period during which the unit of time compressed writing signal is written onto the hard disk does not overlap with a period during which the unit of time compressed reading signal is read from the hard disk apparatus, wherein the time T1 is set to be longer than T, where the time T is defined as a sum of seek time required for moving the magnetic head to write the unit of time compressed writing signal onto the hard disk apparatus, time required for writing the unit of time compressed writing signal onto the hard disk apparatus, seek time required for moving the magnetic head to read the unit of time compressed reading signal from the hard disk apparatus, and time required for reading the unit of time compressed reading signal from the hard disk apparatus.
