Abstract
A carriage fixing apparatus in a disk driver detects that the head carriage which moves a head is located at a predetermined position, and then automatically fixes the head carriage by means of mechanically engaging with the head carriage.
Claims17
A carriage fixing apparatus in a disk driver comprising a head by means of which at least one of recording information on a disk and reproducing information from a disk is carried out, the carriage fixing apparatus comprising:
- first detecting means for detecting a position of a head carriage that moves the head;
- fixing means, responsive to said first detecting means, for automatically fixing the head carriage by mechanically engaging with the head carriage when the first detecting means detects that the head carriage is located at a predetermined position;
- and
- wherein said disk is exchangeably provided to the disk driver, and said carriage fixing apparatus further comprises second detecting means for detecting the presence of the disk, said fixing means fixing the head carriage when said second detecting means detects that the disk is not inserted into the disk driver.

A disk driver comprising:
- a head by means of which at least one of recording information on a disk and reproducing information from a disk is carried out;
- a head carriage that moves said head;
- a carriage fixing apparatus comprising first detecting means for detecting a position of said head carriage and said fixing means, responsive to said first detecting means, for automatically fixing the head carriage by mechanically engaging with the head carriage when the first detecting means detects that the head carriage is located at a predetermined position;
- wherein said disk driver further comprises focus control means for executing a focus controlling of said head based on the detecting result of the first detecting means;
- and
- wherein the focus control means changes a servo gain of a servomechanism of said disk driver based on the detecting result of the first detecting means.

A disk driver, comprising:
- a head by means of which at least one of recording information on a disk and reproducing information from a disk is carried out;
- a head carriage that moves said head;
- a carriage fixing apparatus comprising first detecting means for detecting a position of said head carriage and fixing means, responsive to said first detecting means, for automatically fixing the head carriage by mechanically engaging with the head carriage when the first detecting means detects that the head carriage is located at a predetermined position;
- wherein said disk driver further comprises tracking control means for executing a tracking controlling of said head based on the detecting result of the first detecting means;
- and
- wherein the tracking control means changes a servo gain of a servomechanism of said disk driver based on the detecting result of the first detecting means.
