Reproduction device

A reproduction apparatus comprising:

• a signal reading section for reading a signal recorded in tracks formed on a magnetic tape, the signal including a digital signal and an analog signal;
• a control signal reading section for reading, simultaneously with the reading of the signal, a control signal recorded on the magnetic tape and including information representing a time mode indicating a run speed of the magnetic tape;
• an unrecorded mode determination section for determining whether or not the signal is recorded on the magnetic tape based on the output of the control signal reading section, wherein the output indicates whether or not the control signal is detected;
• a first determination section for determining the time mode based on an output of the control signal reading section;
• a second determination section for determining whether the signal read by the signal reading section is a digital signal or an analog signal after the time mode is determined by the first determination section, wherein the magnetic tape is run in the time mode determined by said first determination section, and a digital/analog determination is made based on a reproduced signal from one pair of magnetic heads;
• and
• a phase control section for controlling the running of the tape so that the signal retains a first phase relationship with the control signal when the signal is a digital signal and that the signal retains a second phase relationship with the control signal when the signal is an analog signal, the second phase relationship being different from the first phase relationship,
• the phase control section controlling the running of the tape so that the first phase relationship is attained prior to the determination by the second determination section as to whether or not the signal read by the signal reading section is a digital signal, and that the second phase relationship is attained prior to the determination by the second determination section as to whether or not the signal read by the signal reading section is an analog signal.

A reproduction apparatus comprising:

• a signal reading section including a rotation cylinder having a magnetic head thereon for reading a signal recorded on a magnetic tape by scanning tracks obliquely formed on the magnetic tape, the signal including a digital signal and an analog signal;
• a tape run speed control section for controlling a run speed of the magnetic tape;
• and
• a reproduction mode determination section for outputting an instruction to the tape run speed control section for running the magnetic tape at a tape run speed different from predetermined tape run speeds used for reading the digital signal or the analog signal and determining whether the signal read by the signal reading section is a digital signal or an analog signal, after running the magnetic tape at the run speed different from predetermined tape run speed used for reading the digital signal or the analog signal.

A reproduction apparatus comprising:

• a signal reading section including a rotation cylinder having a magnetic head thereon for reading a signal recorded on a magnetic tape by scanning tracks obliquely formed on the magnetic tape, the signal including a digital signal and an analog signal;
• a tape run speed control section for controlling the magnetic tape to run or stop;
• and
• a reproduction mode determination section for outputting an instruction to the tape run speed control section for stopping the magnetic tape and determining whether the signal recorded on the magnetic tape is a digital signal or an analog signal based on the signal read by the signal reading section, after stopping the magnetic tape.
