Abstract
An information signal recording apparatus, which includes a pilot signal generator for generating a tracking control pilot signal having a predetermined frequency, a generator for generating an information signal to be recorded, and a recorder for recording the pilot signal on a first area of a recording track, and for recording the information signal on a second area of the recording track. A component of the predetermined frequency of the pilot signal is made to be smaller in a leading portion and in an ending portion of the first area than in other portions of the first area.
Claims11
An information signal recording apparatus, comprising:
- (a) pilot signal generation means for generating a tracking control pilot signal having a predetermined frequency;
- (b) means for generating an information signal to be recorded;
- and
- (c) recording means for recording the pilot signal on a first area of a recording track, and for recording the information signal on a second area of the recording track, wherein a component of the predetermined frequency of the pilot signal is smaller in a leading portion and in an ending portion of the first area than in other portions of the first area.
An information signal recording apparatus, comprising:
- (a) pilot signal generation means for generating a tracking control pilot signal having a predetermined frequency;
- (b) means for generating an information signal to be recorded;
- and
- (c) recording means for recording the pilot signal on a first area of a recording track, and for recording the information signal on a second area of the recording track, wherein an amplitude of the pilot signal is substantially smaller in a leading portion and in an ending portion of the first area than in other portions of the first area.
An information signal recording apparatus, comprising;
- (a) pilot signal generation means for periodically generating a tracking control pilot signal having a predetermined frequency for every predetermined period, a component of the predetermined frequency in the pilot signal being smaller in a leading portion and in an ending portion of the predetermined period than in other portions thereof;
- (b) information generation means for generating an information signal to be recorded;
- (c) multiplexing means for time-division multiplexing the pilot signal and the information signal to form a recording signal;
- and
- (d) recording means for recording the recording signal on a recording medium.
