Abstract
A method of adjusting a magnetic head of the invention includes the steps of: setting a cleaning cartridge into a drive unit; identifying the set cartridge as the cleaning cartridge by checking a cleaning bit in a non-volatile memory; performing an adjustment-operation after a cleaning operation when the set cartridge is identified as the cleaning cartridge; and reading out a pattern signal from a predetermined segment of the magnetic tape held in the cleaning cartridge.
Claims18
A cleaning cartridge, comprising:
- a casing;
- means for identifying itself as the cleaning cartridge;
- and
- a magnetic tape provided with a cleaning and adjustment portion extending from a front end to a rear end and having recorded a magnetically readable pattern signal.
A drive unit for performing writing and reading with respect to a magnetic tape, comprising:
- means for identifying a set cartridge as a cleaning cartridge;
- and
- means for causing said drive unit to perform an adjustment-operation for the magnetic head when the set cartridge is identified as the cleaning cartridge.
A method of adjusting a magnetic head for making adjustments to the magnetic head that performs reading and writing with respect to a magnetic tape, said adjusting method comprising the steps of:
- setting a cleaning cartridge into a drive unit;
- identifying the set cartridge as the cleaning cartridge;
- and
- performing an adjustment-operation for the magnetic head when the set cartridge is identified as the cleaning cartridge.
A magnetic recording system, comprising:
- a cleaning cartridge including means for identifying itself as the cleaning cartridge, and a magnetic tape including a cleaning and adjustment portion extending from a front end to a rear end and has recorded a magnetically readable pattern signal, which are put in a casing;
- and
- a drive unit that need a cleaning operation for a magnetic head for writing and reading out information into and from the magnetic tape, uses said cleaning cartridge to perform cleaning of the magnetic head, and makes adjustments to the magnetic head,
- wherein said drive unit comprises:
- means for identifying a set cartridge as the cleaning cartridge;
- means for causing said drive unit to perform an adjustment-operation for the magnetic head when the set cartridge is identified as the cleaning cartridge;
- means for reading out a pattern signal from a predetermined segment of the magnetic tape held in the cleaning cartridge;
- and
- means for recording the read pattern signal together with time information.
