Title: Recording and reproducing device
Inventor: YOKOYAMA YOSHIHIKO
IPC: G11B5/41
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To enable judging a time of head cleaning by judging a dirty stage of a magnetic head by a compared result between a reproduced signal level when a magnetic head is in a contact and running state for a medium and a reproduced signal level when the magnetic head is in a non-contact state to detect quantitatively a dirty state of a head. SOLUTION: For example, when a frequency is 3kHz, after an output of a non-contact state is passed through a band pass filter (3kHz is passed) 11, an output of a detecting and rectifying circuit 12 is held in a sample-and-hold circuit 13. Next, after an output of a contact and running state is passed through the band pass filter 11, an output of the detecting and rectifying circuit 12 is inputted to an adder 14. And an output of a non-contact state held in the sample-and-hold circuit 13 is inputted to the adder 14. Consequently, a hiss noise component is calculated, a microcomputer 3 judges that a head is not dirty. On the other hand, when a head is dirty, an output of a pre-amplifier 11 is made same as an amplifier noise, and an output of the adder 1 is made the reference value or less.
