    • A PLL frequency synthesizer is provided that enables improvement of near C/N, shortening of lockup time, and reduction of residual FM to be achieved. In this apparatus, phase comparison is performed by a phase comparator (101) on a signal input from an input terminal I1 and a signal output from a frequency divider (107), and a current signal corresponding to the phase difference is converted to a voltage signal by one of a plurality of loop filters (103 or 104) with different cutoff frequencies, and is output to a voltage controlled oscillator (106). The output to a voltage controlled oscillator (106) generates a frequency signal corresponding to the input voltage signal. The. oscillation signal is branched at junction point P1, and is output to the frequency divider (107) and output terminal O1. A variable capacitance capacitor (108) is connected to junction point P2 further branching subsequent to junction point P1 and its capacitance is controlled in accordance with loop filter switching control by a control circuit (109).

    • A control mechanism that loads/unloads data storage tape is part of a tape drive that receives a removable tape cartridge. The tape cartridge stores the data storage tape that is movable using the control mechanism. The control mechanism includes a plurality of gears, together with a cam. A leader assembly is operably connected to the control mechanism. At least portions of the leader assembly are movable in connection with loading or unloading the data storage tape relative to the leader assembly. A leader pin is joined to an end of the data storage tape. When the loading operation is performed, portions of the leader assembly are moved generally linearly into the tape cartridge and then the control mechanism causes such portions to pivot in order to engage the leader pin and remove it from its seat. When the unloading operation is performed, the portions of the leader assembly are moved in substantially opposite directions from the loading operation.
