TAPE DRIVE

摘要

A tape drive comprising first and second motors, the first motor being a torque-controlled motor, two tape spool supports on which spools of tape may be mounted, each spool being drivable by a respective motor, and a controller operable to control the energization of the motors such that tape may be transported in first and second directions between spools mounted on the spool supports. Each spool support is coupled to a respective motor by means of a drive coupling providing at least one fixed transmission ratio. When tape is moved in said first direction, said torque-controlled motor is energised in a first rotational direction, when tape is moved in said second direction, said torque-controlled motor is energised in said first rotational direction for a part of said movement and a second opposite rotational direction for another part of said movement.

1. A tape drive comprising:
first and second motors, the first motor being a torque-controlled motor, two tape spool supports on which spools of tape may be mounted, each spool being drivable by a respective motor, a controller operable to control the energisation of the motors such that tape may be transported in first and second directions between spools mounted on the spool supports, wherein, each spool support is coupled to a respective motor by means of a drive coupling providing at least one fixed transmission ratio; and when tape is moved in said first direction, said torque-controlled motor is energised in a first rotational direction, when tape is moved in said second direction, said torque-controlled motor is energised in said first rotational direction for a part of said movement and a second opposite rotational direction for another part of said movement.
